+                      GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+		         GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions. 
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version. 
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.
+
+--------------------------------------------------------------------------------
+
+              SPECIAL EXCEPTION GRANTED BY IMATIX
+
+As a special exception, iMatix gives you permission to link this library with
+independent modules to produce an executable, regardless of the license terms
+of these independent modules, and to copy and distribute the resulting
+executable under terms of your choice, provided that you also meet, for each
+linked independent module, the terms and conditions of the license of that
+module. An independent module is a module which is not derived from or based on
+this library. If you modify this library, you must extend this exception to your
+version of the library.

+
+    OpenPGM build flags cleanup
+    
+    Removed various exotic -Wxxx flags in the OpenPGM build to get us to what is actually
+    required and reasonable; added in -fno-strict-aliasing since OpenPGM generates lots
+    of warnings about dereferencing typed-punned pointers; removed the OpenPGM extra flags
+    from libzmq_la_CXXFLAGS and left them only in libzmq_la_CFLAGS so that our code
+    is not built with the OpenPGM extra flags.

+
+    Compile perf tests with the C++ compiler
+    
+    This lets us build the binaries in a portable fashion w/o having to worry
+    about how to link with the C++ runtime.

+
+    Build fixes for Solaris and non-GNU compilers
+    
+    Compiling C++ code with -D_POSIX_SOURCE on Solaris is unsupported, so remove it.
+    Isolate GCC-isms inside checks that we are actually using GCC/G++.
+    Only check for -lstdc++ when on GCC and doing static linking.

+    Removed RFC check in debian/rules, again irrelevant to a generic git package.

+
+commit 61ee6fae536a8000be87b5aaf271f6519a3b7d3f
+Author: Martin Hurton <hurtonm@gmail.com>
+Date:   Mon Mar 1 10:13:26 2010 +0100
+
+    Implement flow control
+    
+    This commit introduces the necessary changes necessary
+    for implementing flow control. None of the socket types
+    implements the flow control yet. The code will crash when
+    the flow control is enabled and the thw lwm is reached.
+    
+    The following commits will add flow-control support for
+    individual socket types.

+
+    Use feature test macros more conservatively
+    
+    It turns out that feature test macros are a complete mess, and defining
+    _GNU_SOURCE and _POSIX_C_SOURCE together breaks some systems. So we try
+    and define the appropriate "make everything visible" combination specific
+    to each system instead. This may still break something, so people should
+    test their platforms and speak up if so.

+    This should fix more exotic POSIX platforms such as HPUX which insist on

+    define _GNU_SOURCE so that we get any extensions on systems with glibc, e.g.

+Installation Instructions
+*************************
+
+Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
+2006, 2007 Free Software Foundation, Inc.
+
+This file is free documentation; the Free Software Foundation gives
+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package.  The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+   It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring.  Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'.  You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.
+
+     Running `configure' might take a while.  While running, it prints
+     some messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+  6. Often, you can also type `make uninstall' to remove the installed
+     files again.
+
+Compilers and Options
+=====================
+
+Some systems require unusual options for compilation or linking that the
+`configure' script does not know about.  Run `./configure --help' for
+details on some of the pertinent environment variables.
+
+   You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here
+is an example:
+
+     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you can use GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory.  After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+Installation Names
+==================
+
+By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc.  You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+There may be some features `configure' cannot figure out automatically,
+but needs to determine by the type of machine the package will run on.
+Usually, assuming the package is built to be run on the _same_
+architectures, `configure' can figure that out, but if it prints a
+message saying it cannot guess the machine type, give it the
+`--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS KERNEL-OS
+
+   See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share, you
+can create a site shell script called `config.site' that gives default
+values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug.  Until the bug is fixed you can use this workaround:
+
+     CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+`configure' recognizes the following options to control how it operates.
+
+`--help'
+`-h'
+     Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally `config.cache'.  FILE defaults to `/dev/null' to
+     disable caching.
+
+`--config-cache'
+`-C'
+     Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.

+0MQ version 2.0.7 (Beta), released on 2010/06/04
+================================================
+
+
+Distribution
+------------
+
+* The core documentation has been updated with many clarifications, especially
+  in the description of the functionality provided by the different socket
+  types.
+
+* The version of OpenPGM bundled with 0MQ has been updated to the 2.1.26 release.
+
+
+Building
+--------
+
+* GCC-isms have been removed from the code and build system across the board;
+  0MQ should now build with no issues when using compilers other than GCC.
+
+
+Interface
+---------
+
+* The zmq_init() function now has only a single parameter; the number of 0MQ
+  I/O threads to create in the context being initialised. The app_threads and
+  flags parameters have been removed.
+
+* The ZMQ_P2P socket type has been renamed to ZMQ_PAIR.
+
+* The ZMQ_LWM socket option has been removed; the low water mark for a socket
+  is now computed automatically by 0MQ.
+
+* A zmq_getsockopt() function has been added.
+
+
+New functionality
+-----------------
+
+* Multi-hop request/reply is fully supported. This feature allows the insertion
+  of device(s) between ZMQ_REQ and ZMQ_REP sockets thus enabling scenarios
+  such as multi-threaded server, shared service queue, and other interesting
+  messaging topologies. The entire infrastructure is transparent to
+  applications.
+
+* Multi-part messages.  A 0MQ message may now be composed of 1 or more message
+  parts; each message part is an independent zmq_msg_t in its own right. 0MQ
+  ensures atomic delivery of messages; peers shall receive either all message
+  parts of a message or none at all.
+
+  This feature allows for seamless zero-copy message passing when data are
+  scattered in memory, and is an important building block for multi-hop
+  messaging topologies.
+
+* Context termination and ETERM. The zmq_term() function has been
+  changed to interrupt any blocking operations on open sockets, causing them to
+  return the newly defined ETERM error code. This allows for orderly
+  application termination, especially when multiple application threads are
+  involved.
+
+
+0MQ version 2.0.6 (Beta), released on 2010/03/16
+================================================
+
+
+Distribution
+------------
+
+* The 0MQ core distribution has been slimmed down to include only the core
+  C library and C++ language binding. Pointers to other language bindings can
+  be found on the website. Examples have also been removed from the
+  core and can be found elsewhere. Performance tests specific to a language
+  binding can be found bundled with that language binding.
+
+* The 0MQ reference manual supplied with the distribution has been
+  extensively rewritten, and is now provided in HTML as well as UNIX
+  manpage format.
+
+* Commencing with this release, a 0MQ version numbering scheme has been
+  introduced. The numbering scheme used is MAJOR.MINOR.PATCH. The "Beta" or
+  "Stable" label is informative only and does not constitute
+  part of the library version number, therefore this release is numbered
+  2.0.6 as the sixth release of 2.0.
+
+* The version of OpenPGM bundled with 0MQ has been updated to the stable
+  2.0.24 release.
+
+
+Building
+--------
+
+* Many portability fixes, including support for new platforms: FreeBSD, 
+  NetBSD, HP-UX and Cygwin.
+
+* Invocation of configure has been simplified, all functionality is now
+  built by default with the exception of OpenPGM.
+
+
+Interface
+---------
+
+* The udp transport has been renamed to epgm to avoid confusion with
+  unreliable unicast.
+
+* A ZMQ_POLLERR constant has been added to allow for polling on errors on
+  Berkeley sockets with zmq_poll().
+
+* The zmq_version() function has been introduced and returns the version
+  number of the 0MQ library.
+
+* The zmq_flush() function and ZMQ_NOFLUSH flag of zmq_send() have been
+  deprecated and will be removed in a future release.
+
+
+Wire format
+-----------
+
+* The 0MQ wire format has been changed. A flags field has been added to
+  allow for future extensions.
+
+
+New functionality
+-----------------
+
+* The experimental ZMQ_P2P socket type has been implemented.
+
+* Flow control has been implemented for all socket types. For details see
+  the ZMQ_HWM and ZMQ_LWM socket options.
+
+* Subscription filters are internally matched with O(1) complexity.
+
+
+Licensing
+---------
+
+* iMatix corporation has granted the following exception regarding static
+  linking with the 0MQ library:
+
+    As a special exception, iMatix gives you permission to link this
+    library with independent modules to produce an executable,
+    regardless of the license terms of these independent modules, and
+    to copy and distribute the resulting executable under terms of
+    your choice, provided that you also meet, for each linked
+    independent module, the terms and conditions of the license of
+    that module. An independent module is a module which is not
+    derived from or based on this library.  If you modify this
+    library, you must extend this exception to your version of the
+    library.
+
+
+Thanks to
+---------
+
+This release of 0MQ was made possible by many contributors from the community,
+including:
+
+* Adrian von Bidder <avbidder@fortytwo.ch>, for contributing Debian packages.
+
+* Aleksey Yeschenko <aleksey@yeschenko.com>, for contributing a Lua binding.

+
+The 0MQ lightweight messaging kernel is a library which extends the
+standard socket interfaces with features traditionally provided by
+specialised messaging middleware products. 0MQ sockets provide an
+abstraction of asynchronous message queues, multiple messaging patterns,
+message filtering (subscriptions), seamless access to multiple transport
+protocols and more.
+
+

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a

+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)

+# So we provide this file, which has a silly filename so it's always
+# included after everything else.  This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point

+\`configure' configures zeromq 2.0.7 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+			  [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+			  [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:

+.SH "NAME"
+zmq \- 0MQ lightweight messaging kernel
+.SH "SYNOPSIS"
+.sp
+\fB#include <zmq\&.h>\fR
+.sp
+\fBcc\fR [\fIflags\fR] \fIfiles\fR \fB\-lzmq\fR [\fIlibraries\fR]
+.SH "DESCRIPTION"
+.sp
+The 0MQ lightweight messaging kernel is a library which extends the standard socket interfaces with features traditionally provided by specialised \fImessaging middleware\fR products\&. 0MQ sockets provide an abstraction of asynchronous \fImessage queues\fR, multiple \fImessaging patterns\fR, message filtering (\fIsubscriptions\fR), seamless access to multiple \fItransport protocols\fR and more\&.
+.sp
+This documentation presents an overview of 0MQ concepts, describes how 0MQ abstracts standard sockets and provides a reference manual for the functions provided by the 0MQ library\&.
+.SS "Context"
+.sp
+Before using any 0MQ library functions the caller must initialise a 0MQ \fIcontext\fR using \fIzmq_init()\fR\&. The following functions are provided to handle initialisation and termination of a \fIcontext\fR:
+.PP
+Initialise 0MQ context
+.RS 4
+
+\fBzmq_init\fR(3)
+.RE
+.PP
+Terminate 0MQ context
+.RS 4
+
+\fBzmq_term\fR(3)
+.RE
+.sp
+.it 1 an-trap
+.nr an-no-space-flag 1
+.nr an-break-flag 1
+.br
+.ps +1
+\fBThread safety\fR
+.RS 4
+.sp
+A 0MQ \fIcontext\fR is thread safe and may be shared among as many application threads as the application has requested using the \fIapp_threads\fR parameter to \fIzmq_init()\fR, without any additional locking required on the part of the caller\&. Each 0MQ socket belonging to a particular \fIcontext\fR may only be used by \fBthe thread that created it\fR using \fIzmq_socket()\fR\&.
+.RE
+.sp
+.it 1 an-trap
+.nr an-no-space-flag 1
+.nr an-break-flag 1
+.br
+.ps +1
+\fBMultiple contexts\fR
+.RS 4
+.sp
+Multiple \fIcontexts\fR may coexist within a single application\&. Thus, an application can use 0MQ directly and at the same time make use of any number of additional libraries or components which themselves make use of 0MQ as long as the above guidelines regarding thread safety are adhered to\&.
+.RE
+.SS "Messages"
+.sp
+A 0MQ message is a discrete unit of data passed between applications or components of the same application\&. 0MQ messages have no internal structure and from the point of view of 0MQ itself they are considered to be opaque binary data\&.
+.sp
+The following functions are provided to work with messages:
+.PP
+Initialise a message
+.RS 4
+
+\fBzmq_msg_init\fR(3)
+\fBzmq_msg_init_size\fR(3)
+\fBzmq_msg_init_data\fR(3)
+.RE
+.PP
+Release a message
+.RS 4
+
+\fBzmq_msg_close\fR(3)
+.RE
+.PP
+Access message content
+.RS 4
+
+\fBzmq_msg_data\fR(3)
+\fBzmq_msg_size\fR(3)
+.RE
+.PP
+Message manipulation
+.RS 4
+
+\fBzmq_msg_copy\fR(3)
+\fBzmq_msg_move\fR(3)
+.RE
+.SS "Sockets"
+.sp
+0MQ sockets present an abstraction of a asynchronous \fImessage queue\fR, with the exact queueing semantics depending on the socket type in use\&. See \fBzmq_socket\fR(3) for the socket types provided\&.
+.sp
+The following functions are provided to work with sockets:
+.PP
+Creating a socket
+.RS 4
+
+\fBzmq_socket\fR(3)
+.RE
+.PP
+Closing a socket
+.RS 4
+
+\fBzmq_close\fR(3)
+.RE
+.PP
+Manipulating socket options
+.RS 4
+
+\fBzmq_getsockopt\fR(3)
+\fBzmq_setsockopt\fR(3)
+.RE
+.PP
+Establishing a message flow
+.RS 4
+
+\fBzmq_bind\fR(3)
+\fBzmq_connect\fR(3)
+.RE
+.PP
+Sending and receiving messages
+.RS 4
+
+\fBzmq_send\fR(3)
+\fBzmq_recv\fR(3)
+.RE
+.PP
+\fBInput/output multiplexing\fR. 0MQ provides a mechanism for applications to multiplex input/output events over a set containing both 0MQ sockets and standard sockets\&. This mechanism mirrors the standard
+\fIpoll()\fR
+system call, and is described in detail in
+\fBzmq_poll\fR(3)\&.
+.SS "Transports"
+.sp
+A 0MQ socket can use multiple different underlying transport mechanisms\&. Each transport mechanism is suited to a particular purpose and has its own advantages and drawbacks\&.
+.sp
+The following transport mechanisms are provided:
+.PP
+Unicast transport using TCP
+.RS 4
+
+\fBzmq_tcp\fR(7)
+.RE
+.PP
+Reliable multicast transport using PGM
+.RS 4
+
+\fBzmq_pgm\fR(7)
+.RE
+.PP
+Local inter\-process communication transport
+.RS 4
+
+\fBzmq_ipc\fR(7)
+.RE
+.PP
+Local in\-process (inter\-thread) communication transport
+.RS 4
+
+\fBzmq_inproc\fR(7)
+.RE
+.SS "Devices"
+.sp
+Apart from the 0MQ library the 0MQ distribution includes \fIdevices\fR which are building blocks intended to serve as intermediate nodes in complex messaging topologies\&.
+.sp
+The following devices are provided:
+.PP
+Forwarder device for request\-response messaging
+.RS 4
+
+\fBzmq_queue\fR(1)
+.RE
+.PP
+Forwarder device for publish\-subscribe messaging
+.RS 4
+
+\fBzmq_forwarder\fR(1)
+.RE
+.PP
+Streamer device for parallelized pipeline messaging
+.RS 4
+
+\fBzmq_streamer\fR(1)
+.RE
+.SH "ERROR HANDLING"
+.sp
+The 0MQ library functions handle errors using the standard conventions found on POSIX systems\&. Generally, this means that upon failure a 0MQ library function shall return either a NULL value (if returning a pointer) or a negative value (if returning an integer), and the actual error code shall be stored in the \fIerrno\fR variable\&.
+.sp
+On non\-POSIX systems some users may experience issues with retrieving the correct value of the \fIerrno\fR variable\&. The \fIzmq_errno()\fR function is provided to assist in these cases; for details refer to \fBzmq_errno\fR(3)\&.
+.sp
+The \fIzmq_strerror()\fR function is provided to translate 0MQ\-specific error codes into error message strings; for details refer to \fBzmq_strerror\fR(3)\&.
+.SH "MISCELLANEOUS"
+.sp
+The following miscellaneous functions are provided:
+.PP
+Report 0MQ library version
+.RS 4
+
+\fBzmq_version\fR(3)
+.RE
+.SH "LANGUAGE BINDINGS"
+.sp
+The 0MQ library provides interfaces suitable for calling from programs in any language; this documentation documents those interfaces as they would be used by C programmers\&. The intent is that programmers using 0MQ from other languages shall refer to this documentation alongside any documentation provided by the vendor of their language binding\&.
+.SS "C++ language binding"
+.sp
+The 0MQ distribution includes a C++ language binding, which is documented separately in \fBzmq_cpp\fR(7)\&.
+.SS "Other language bindings"
+.sp
+Other language bindings (Python, Ruby, Java and more) are provided by members of the 0MQ community and pointers can be found on the 0MQ website\&.
+.SH "AUTHORS"
+.sp
+The 0MQ documentation was written by Martin Sustrik <\m[blue]\fBsustrik@250bpm\&.com\fR\m[]\&\s-2\u[1]\d\s+2> and Martin Lucina <\m[blue]\fBmato@kotelna\&.sk\fR\m[]\&\s-2\u[2]\d\s+2>\&.

+zmq - 0MQ lightweight messaging kernel
+
+
+SYNOPSIS
+--------
+*#include <zmq.h>*
+
+*cc* ['flags'] 'files' *-lzmq* ['libraries']
+
+
+DESCRIPTION
+-----------
+The 0MQ lightweight messaging kernel is a library which extends the standard
+socket interfaces with features traditionally provided by specialised
+_messaging middleware_ products. 0MQ sockets provide an abstraction of
+asynchronous  _message queues_, multiple _messaging patterns_, message
+filtering (_subscriptions_), seamless access to multiple _transport protocols_
+and more.
+
+This documentation presents an overview of 0MQ concepts, describes how 0MQ
+abstracts standard sockets and provides a reference manual for the functions
+provided by the 0MQ library.
+
+
+Context
+~~~~~~~
+Before using any 0MQ library functions the caller must initialise a 0MQ
+'context' using _zmq_init()_. The following functions are provided to handle
+initialisation and termination of a 'context':
+
+Initialise 0MQ context::
+    linkzmq:zmq_init[3]
+
+Terminate 0MQ context::
+    linkzmq:zmq_term[3]
+
+
+Thread safety
+^^^^^^^^^^^^^
+A 0MQ 'context' is thread safe and may be shared among as many application
+threads as the application has requested using the _app_threads_ parameter to
+_zmq_init()_, without any additional locking required on the part of the
+caller.  Each 0MQ socket belonging to a particular 'context' may only be used
+by *the thread that created it* using _zmq_socket()_.
+
+
+Multiple contexts
+^^^^^^^^^^^^^^^^^
+Multiple 'contexts' may coexist within a single application. Thus, an
+application can use 0MQ directly and at the same time make use of any number of
+additional libraries or components which themselves make use of 0MQ as long as
+the above guidelines regarding thread safety are adhered to.
+
+
+Messages
+~~~~~~~~
+A 0MQ message is a discrete unit of data passed between applications or
+components of the same application. 0MQ messages have no internal structure and
+from the point of view of 0MQ itself they are considered to be opaque binary
+data.
+
+The following functions are provided to work with messages:
+
+Initialise a message::
+    linkzmq:zmq_msg_init[3]
+    linkzmq:zmq_msg_init_size[3]
+    linkzmq:zmq_msg_init_data[3]
+
+Release a message::
+    linkzmq:zmq_msg_close[3]
+
+Access message content::
+    linkzmq:zmq_msg_data[3]
+    linkzmq:zmq_msg_size[3]
+
+Message manipulation::
+    linkzmq:zmq_msg_copy[3]
+    linkzmq:zmq_msg_move[3]
+
+
+Sockets
+~~~~~~~
+0MQ sockets present an abstraction of a asynchronous _message queue_, with the
+exact queueing semantics depending on the socket type in use. See
+linkzmq:zmq_socket[3] for the socket types provided.
+
+The following functions are provided to work with sockets:
+
+Creating a socket::
+    linkzmq:zmq_socket[3]
+
+Closing a socket::
+    linkzmq:zmq_close[3]
+
+Manipulating socket options::
+    linkzmq:zmq_getsockopt[3]
+    linkzmq:zmq_setsockopt[3]

+
+.Input/output multiplexing
+0MQ provides a mechanism for applications to multiplex input/output events over
+a set containing both 0MQ sockets and standard sockets. This mechanism mirrors
+the standard _poll()_ system call, and is described in detail in
+linkzmq:zmq_poll[3].
+
+
+Transports
+~~~~~~~~~~
+A 0MQ socket can use multiple different underlying transport mechanisms.
+Each transport mechanism is suited to a particular purpose and has its own
+advantages and drawbacks.
+
+The following transport mechanisms are provided:
+
+Unicast transport using TCP::
+    linkzmq:zmq_tcp[7]
+
+Reliable multicast transport using PGM::
+    linkzmq:zmq_pgm[7]
+
+Local inter-process communication transport::
+    linkzmq:zmq_ipc[7]
+
+Local in-process (inter-thread) communication transport::
+    linkzmq:zmq_inproc[7]
+
+
+Devices
+~~~~~~~
+Apart from the 0MQ library the 0MQ distribution includes 'devices' which are
+building blocks intended to serve as intermediate nodes in complex messaging
+topologies.
+
+The following devices are provided:
+
+Forwarder device for request-response messaging::
+    linkzmq:zmq_queue[1]
+
+Forwarder device for publish-subscribe messaging::
+    linkzmq:zmq_forwarder[1]
+
+Streamer device for parallelized pipeline messaging::
+    linkzmq:zmq_streamer[1]
+
+
+ERROR HANDLING
+--------------
+The 0MQ library functions handle errors using the standard conventions found on
+POSIX systems. Generally, this means that upon failure a 0MQ library function
+shall return either a NULL value (if returning a pointer) or a negative value
+(if returning an integer), and the actual error code shall be stored in the
+'errno' variable.
+
+On non-POSIX systems some users may experience issues with retrieving the
+correct value of the 'errno' variable. The _zmq_errno()_ function is provided
+to assist in these cases; for details refer to linkzmq:zmq_errno[3].
+
+The _zmq_strerror()_ function is provided to translate 0MQ-specific error codes
+into error message strings; for details refer to linkzmq:zmq_strerror[3].
+
+
+MISCELLANEOUS
+-------------
+The following miscellaneous functions are provided:
+
+Report 0MQ library version::
+    linkzmq:zmq_version[3]
+
+
+LANGUAGE BINDINGS
+-----------------
+The 0MQ library provides interfaces suitable for calling from programs in any
+language; this documentation documents those interfaces as they would be used
+by C programmers. The intent is that programmers using 0MQ from other languages
+shall refer to this documentation alongside any documentation provided by the
+vendor of their language binding.
+
+
+C++ language binding
+~~~~~~~~~~~~~~~~~~~~
+The 0MQ distribution includes a $$C++$$ language binding, which is documented
+separately in linkzmq:zmq_cpp[7].
+
+
+Other language bindings
+~~~~~~~~~~~~~~~~~~~~~~~
+Other language bindings (Python, Ruby, Java and more) are provided by members
+of the 0MQ community and pointers can be found on the 0MQ website.

+.SH "NAME"
+zmq_bind \- accept connections on a socket
+.SH "SYNOPSIS"
+.sp
+\fBint zmq_bind (void \fR\fB\fI*socket\fR\fR\fB, const char \fR\fB\fI*endpoint\fR\fR\fB);\fR
+.SH "DESCRIPTION"
+.sp
+The \fIzmq_bind()\fR function shall create an endpoint for accepting connections and bind it to the socket referenced by the \fIsocket\fR argument\&.
+.sp
+The \fIendpoint\fR argument is a string consisting of two parts as follows: \fItransport\fR://\fIaddress\fR\&. The \fItransport\fR part specifies the underlying transport protocol to use\&. The meaning of the \fIaddress\fR part is specific to the underlying transport protocol selected\&.
+.sp
+The following transports are defined:
+.PP
+\fIinproc\fR
+.RS 4
+local in\-process (inter\-thread) communication transport, see
+\fBzmq_inproc\fR(7)
+.RE
+.PP
+\fIipc\fR
+.RS 4
+local inter\-process communication transport, see
+\fBzmq_ipc\fR(7)
+.RE
+.PP
+\fItcp\fR
+.RS 4
+unicast transport using TCP, see
+\fBzmq_tcp\fR(7)
+.RE
+.PP
+\fIpgm\fR, \fIepgm\fR
+.RS 4
+reliable multicast transport using PGM, see
+\fBzmq_pgm\fR(7)
+.RE
+.sp
+With the exception of \fIZMQ_PAIR\fR sockets, a single socket may be connected to multiple endpoints using \fIzmq_connect()\fR, while simultaneously accepting incoming connections from multiple endpoints bound to the socket using \fIzmq_bind()\fR\&. Refer to \fBzmq_socket\fR(3) for a description of the exact semantics involved when connecting or binding a socket to multiple endpoints\&.
+.SH "RETURN VALUE"
+.sp
+The \fIzmq_bind()\fR function shall return zero if successful\&. Otherwise it shall return \-1 and set \fIerrno\fR to one of the values defined below\&.
+.SH "ERRORS"
+.PP
+\fBEPROTONOSUPPORT\fR
+.RS 4
+The requested
+\fItransport\fR
+protocol is not supported\&.
+.RE
+.PP
+\fBENOCOMPATPROTO\fR
+.RS 4
+The requested
+\fItransport\fR
+protocol is not compatible with the socket type\&.
+.RE
+.PP
+\fBEADDRINUSE\fR
+.RS 4
+The requested
+\fIaddress\fR
+is already in use\&.
+.RE
+.PP
+\fBEADDRNOTAVAIL\fR
+.RS 4
+The requested
+\fIaddress\fR
+was not local\&.
+.RE
+.PP
+\fBENODEV\fR

+zmq_bind(3)
+===========
+
+
+NAME
+----
+zmq_bind - accept connections on a socket
+
+
+SYNOPSIS
+--------
+*int zmq_bind (void '*socket', const char '*endpoint');*
+
+
+DESCRIPTION
+-----------
+The _zmq_bind()_ function shall create an endpoint for accepting connections
+and bind it to the socket referenced by the 'socket' argument.
+
+The 'endpoint' argument is a string consisting of two parts as follows:
+'transport'`://`'address'. The 'transport' part specifies the underlying
+transport protocol to use. The meaning of the 'address' part is specific to
+the underlying transport protocol selected.
+
+The following transports are defined:
+
+'inproc':: local in-process (inter-thread) communication transport, see linkzmq:zmq_inproc[7]
+'ipc':: local inter-process communication transport, see linkzmq:zmq_ipc[7]
+'tcp':: unicast transport using TCP, see linkzmq:zmq_tcp[7]
+'pgm', 'epgm':: reliable multicast transport using PGM, see linkzmq:zmq_pgm[7]
+
+With the exception of 'ZMQ_PAIR' sockets, a single socket may be connected to
+multiple endpoints using _zmq_connect()_, while simultaneously accepting
+incoming connections from multiple endpoints bound to the socket using
+_zmq_bind()_. Refer to linkzmq:zmq_socket[3] for a description of the exact
+semantics involved when connecting or binding a socket to multiple endpoints.
+
+
+RETURN VALUE
+------------
+The _zmq_bind()_ function shall return zero if successful. Otherwise it shall
+return `-1` and set 'errno' to one of the values defined below.
+
+
+ERRORS
+------
+*EPROTONOSUPPORT*::
+The requested 'transport' protocol is not supported.
+*ENOCOMPATPROTO*::
+The requested 'transport' protocol is not compatible with the socket type.
+*EADDRINUSE*::
+The requested 'address' is already in use.
+*EADDRNOTAVAIL*::
+The requested 'address' was not local.
+*ENODEV*::
+The requested 'address' specifies a nonexistent interface.
+*ETERM*::
+The 0MQ 'context' associated with the specified 'socket' was terminated.
+
+
+EXAMPLE
+-------
+.Binding a publisher socket to an in-process and a TCP transport
+----
+/* Create a ZMQ_PUB socket */
+void *socket = zmq_socket (context, ZMQ_PUB);
+assert (socket);
+/* Bind it to a in-process transport with the address 'my_publisher' */
+int rc = zmq_bind (socket, "inproc://my_publisher");
+assert (rc == 0);
+/* Bind it to a TCP transport on port 5555 of the 'eth0' interface */
+rc = zmq_bind (socket, "tcp://eth0:5555");

+zmq_connect \- connect a socket
+.SH "SYNOPSIS"
+.sp
+\fBint zmq_connect (void \fR\fB\fI*socket\fR\fR\fB, const char \fR\fB\fI*endpoint\fR\fR\fB);\fR
+.SH "DESCRIPTION"
+.sp
+The \fIzmq_connect()\fR function shall connect the socket referenced by the \fIsocket\fR argument to the endpoint specified by the \fIendpoint\fR argument\&.
+.sp
+The \fIendpoint\fR argument is a string consisting of two parts as follows: \fItransport\fR://\fIaddress\fR\&. The \fItransport\fR part specifies the underlying transport protocol to use\&. The meaning of the \fIaddress\fR part is specific to the underlying transport protocol selected\&.
+.sp
+The following transports are defined:
+.PP
+\fIinproc\fR
+.RS 4
+local in\-process (inter\-thread) communication transport, see
+\fBzmq_inproc\fR(7)
+.RE
+.PP
+\fIipc\fR
+.RS 4
+local inter\-process communication transport, see
+\fBzmq_ipc\fR(7)
+.RE
+.PP
+\fItcp\fR
+.RS 4
+unicast transport using TCP, see
+\fBzmq_tcp\fR(7)
+.RE
+.PP
+\fIpgm\fR, \fIepgm\fR
+.RS 4
+reliable multicast transport using PGM, see
+\fBzmq_pgm\fR(7)
+.RE
+.sp
+With the exception of \fIZMQ_PAIR\fR sockets, a single socket may be connected to multiple endpoints using \fIzmq_connect()\fR, while simultaneously accepting incoming connections from multiple endpoints bound to the socket using \fIzmq_bind()\fR\&. Refer to \fBzmq_socket\fR(3) for a description of the exact semantics involved when connecting or binding a socket to multiple endpoints\&.
+.if n \{\
+.sp
+.\}

+.it 1 an-trap
+.nr an-no-space-flag 1
+.nr an-break-flag 1
+.br
+.ps +1
+\fBNote\fR
+.ps -1
+.br
+.sp
+The connection will not be performed immediately but as needed by 0MQ\&. Thus a successful invocation of \fIzmq_connect()\fR does not indicate that a physical connection was or can actually be established\&.
+.sp .5v
+.RE
+.SH "RETURN VALUE"
+.sp
+The \fIzmq_connect()\fR function shall return zero if successful\&. Otherwise it shall return \-1 and set \fIerrno\fR to one of the values defined below\&.
+.SH "ERRORS"

+\fItransport\fR
+protocol is not supported\&.
+.RE

+\fItransport\fR
+protocol is not compatible with the socket type\&.

+NAME
+----
+zmq_connect - connect a socket
+
+
+SYNOPSIS
+--------
+*int zmq_connect (void '*socket', const char '*endpoint');*
+
+
+DESCRIPTION
+-----------
+The _zmq_connect()_ function shall connect the socket referenced by the
+'socket' argument to the endpoint specified by the 'endpoint' argument.
+
+The 'endpoint' argument is a string consisting of two parts as follows:
+'transport'`://`'address'. The 'transport' part specifies the underlying
+transport protocol to use. The meaning of the 'address' part is specific to
+the underlying transport protocol selected.
+
+The following transports are defined:
+
+'inproc':: local in-process (inter-thread) communication transport, see linkzmq:zmq_inproc[7]
+'ipc':: local inter-process communication transport, see linkzmq:zmq_ipc[7]
+'tcp':: unicast transport using TCP, see linkzmq:zmq_tcp[7]
+'pgm', 'epgm':: reliable multicast transport using PGM, see linkzmq:zmq_pgm[7]
+
+With the exception of 'ZMQ_PAIR' sockets, a single socket may be connected to
+multiple endpoints using _zmq_connect()_, while simultaneously accepting
+incoming connections from multiple endpoints bound to the socket using
+_zmq_bind()_. Refer to linkzmq:zmq_socket[3] for a description of the exact
+semantics involved when connecting or binding a socket to multiple endpoints.
+
+NOTE: The connection will not be performed immediately but as needed by 0MQ.
+Thus a successful invocation of _zmq_connect()_ does not indicate that a
+physical connection was or can actually be established.
+
+
+RETURN VALUE
+------------
+The _zmq_connect()_ function shall return zero if successful. Otherwise it
+shall return `-1` and set 'errno' to one of the values defined below.
+
+
+ERRORS
+------
+*EPROTONOSUPPORT*::
+The requested 'transport' protocol is not supported.
+*ENOCOMPATPROTO*::
+The requested 'transport' protocol is not compatible with the socket type.
+*ETERM*::
+The 0MQ 'context' associated with the specified 'socket' was terminated.
+
+
+EXAMPLE
+-------
+.Connecting a subscriber socket to an in-process and a TCP transport
+----
+/* Create a ZMQ_SUB socket */
+void *socket = zmq_socket (context, ZMQ_SUB);
+assert (socket);
+/* Connect it to an in-process transport with the address 'my_publisher' */
+int rc = zmq_connect (socket, "inproc://my_publisher");
+assert (rc == 0);
+/* Connect it to the host server001, port 5555 using a TCP transport */

+.SH "NAME"
+zmq_pgm \- 0MQ reliable multicast transport using PGM
+.SH "SYNOPSIS"
+.sp
+PGM (Pragmatic General Multicast) is a protocol for reliable multicast transport of data over IP networks\&.
+.SH "DESCRIPTION"
+.sp
+0MQ implements two variants of PGM, the standard protocol where PGM datagrams are layered directly on top of IP datagrams as defined by RFC 3208 (the \fIpgm\fR transport) and "Encapsulated PGM" where PGM datagrams are encapsulated inside UDP datagrams (the \fIepgm\fR transport)\&.
+.sp
+The \fIpgm\fR and \fIepgm\fR transports can only be used with the \fIZMQ_PUB\fR and \fIZMQ_SUB\fR socket types\&.
+.sp
+Further, PGM sockets are rate limited by default and incur a performance penalty when used over a loopback interface\&. For details, refer to the \fIZMQ_RATE\fR, \fIZMQ_RECOVERY_IVL\fR and \fIZMQ_MCAST_LOOP\fR options documented in \fBzmq_setsockopt\fR(3)\&.
+.if n \{\
+.sp
+.\}
+.RS 4
+.it 1 an-trap
+.nr an-no-space-flag 1
+.nr an-break-flag 1
+.br
+.ps +1
+\fBCaution\fR
+.ps -1
+.br
+.sp
+The \fIpgm\fR transport implementation requires access to raw IP sockets\&. Additional privileges may be required on some operating systems for this operation\&. Applications not requiring direct interoperability with other PGM implementations are encouraged to use the \fIepgm\fR transport instead which does not require any special privileges\&.
+.sp .5v
+.RE
+.SH "ADDRESSING"
+.sp
+A 0MQ address string consists of two parts as follows: \fItransport\fR://\fIendpoint\fR\&. The \fItransport\fR part specifies the underlying transport protocol to use\&. For the standard PGM protocol, \fItransport\fR shall be set to pgm\&. For the "Encapsulated PGM" protocol \fItransport\fR shall be set to epgm\&. The meaning of the \fIendpoint\fR part for both the \fIpgm\fR and \fIepgm\fR transport is defined below\&.
+.SS "Connecting a socket"
+.sp
+When connecting a socket to a peer address using \fIzmq_connect()\fR with the \fIpgm\fR or \fIepgm\fR transport, the \fIendpoint\fR shall be interpreted as an \fIinterface\fR followed by a semicolon, followed by a \fImulticast address\fR, followed by a colon and a port number\&.
+.sp
+An \fIinterface\fR may be specified by either of the following:
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+The interface name as defined by the operating system\&.
+.RE
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+The primary IPv4 address assigned to the interface, in it\(cqs numeric representation\&.
+.RE
+.if n \{\
+.sp
+.\}
+.RS 4
+.it 1 an-trap
+.nr an-no-space-flag 1
+.nr an-break-flag 1
+.br
+.ps +1
+\fBNote\fR
+.ps -1
+.br
+.sp
+Interface names are not standardised in any way and should be assumed to be arbitrary and platform dependent\&. On Win32 platforms no short interface names exist, thus only the primary IPv4 address may be used to specify an \fIinterface\fR\&.
+.sp .5v
+.RE
+.sp
+A \fImulticast address\fR is specified by an IPv4 multicast address in it\(cqs numeric representation\&.
+.SH "WIRE FORMAT"
+.sp
+Consecutive PGM datagrams are interpreted by 0MQ as a single continous stream of data where 0MQ messages are not necessarily aligned with PGM datagram boundaries and a single 0MQ message may span several PGM datagrams\&. This stream of data consists of 0MQ messages encapsulated in \fIframes\fR as described in \fBzmq_tcp\fR(7)\&.
+.SS "PGM datagram payload"
+.sp
+The following ABNF grammar represents the payload of a single PGM datagram as used by 0MQ:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+datagram               = (offset data)
+offset                 = 2OCTET
+data                   = *OCTET
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+In order for late joining consumers to be able to identify message boundaries, each PGM datagram payload starts with a 16\-bit unsigned integer in network byte order specifying either the offset of the first message \fIframe\fR in the datagram or containing the value 0xFFFF if the datagram contains solely an intermediate part of a larger message\&.
+.sp
+The following diagram illustrates the layout of a single PGM datagram payload:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
++\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+

+.fi
+.if n \{\
+.RE
+.\}
+.sp
+The following diagram further illustrates how three example 0MQ frames are laid out in consecutive PGM datagram payloads:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf

+<h2 id="_synopsis">SYNOPSIS</h2>

+<div class="sectionbody">

+<div class="paragraph"><p>PGM (Pragmatic General Multicast) is a protocol for reliable multicast

+transport of data over IP networks.</p></div>

+</div>

+<h2 id="_description">DESCRIPTION</h2>

+<div class="sectionbody">

+<div class="paragraph"><p>ØMQ implements two variants of PGM, the standard protocol where PGM datagrams

+are layered directly on top of IP datagrams as defined by RFC 3208 (the <em>pgm</em>

+transport) and "Encapsulated PGM" where PGM datagrams are encapsulated inside

+UDP datagrams (the <em>epgm</em> transport).</p></div>

+<div class="paragraph"><p>The <em>pgm</em> and <em>epgm</em> transports can only be used with the <em>ZMQ_PUB</em> and

+<em>ZMQ_SUB</em> socket types.</p></div>

+<div class="paragraph"><p>Further, PGM sockets are rate limited by default and incur a performance

+penalty when used over a loopback interface. For details, refer to the

+<em>ZMQ_RATE</em>, <em>ZMQ_RECOVERY_IVL</em> and <em>ZMQ_MCAST_LOOP</em> options documented in

+<a href="zmq_setsockopt.html">zmq_setsockopt(3)</a>.</p></div>

+<div class="admonitionblock">

+<table><tr>

+<td class="icon">

+<div class="title">Caution</div>

+</td>

+<td class="content">The <em>pgm</em> transport implementation requires access to raw IP sockets.

+Additional privileges may be required on some operating systems for this

+operation. Applications not requiring direct interoperability with other PGM

+implementations are encouraged to use the <em>epgm</em> transport instead which does

+not require any special privileges.</td>

+</tr></table>

+</div>

+</div>

+<h2 id="_addressing">ADDRESSING</h2>

+<div class="sectionbody">

+<div class="paragraph"><p>A ØMQ address string consists of two parts as follows:

+<em>transport</em><tt>://</tt><em>endpoint</em>. The <em>transport</em> part specifies the underlying

+transport protocol to use. For the standard PGM protocol, <em>transport</em> shall be

+set to <tt>pgm</tt>. For the "Encapsulated PGM" protocol <em>transport</em> shall be set to

+<tt>epgm</tt>. The meaning of the <em>endpoint</em> part for both the <em>pgm</em> and <em>epgm</em>

+transport is defined below.</p></div>

+<h3 id="_connecting_a_socket">Connecting a socket</h3><div style="clear:left"></div>

+<div class="paragraph"><p>When connecting a socket to a peer address using <em>zmq_connect()</em> with the <em>pgm</em>

+or <em>epgm</em> transport, the <em>endpoint</em> shall be interpreted as an <em>interface</em>

+followed by a semicolon, followed by a <em>multicast address</em>, followed by a colon

+and a port number.</p></div>

+<div class="paragraph"><p>An <em>interface</em> may be specified by either of the following:</p></div>

+<div class="ulist"><ul>

+<li>

+<p>

+The interface name as defined by the operating system.

+</p>

+</li>

+<li>

+<p>

+The primary IPv4 address assigned to the interface, in it&#8217;s numeric

+  representation.

+</p>

+</li>

+</ul></div>

+<div class="admonitionblock">

+<table><tr>

+<td class="icon">

+<div class="title">Note</div>

+</td>

+<td class="content">Interface names are not standardised in any way and should be assumed to

+be arbitrary and platform dependent. On Win32 platforms no short interface

+names exist, thus only the primary IPv4 address may be used to specify an

+<em>interface</em>.</td>

+<div class="sectionbody">

+<div class="paragraph"><p>Consecutive PGM datagrams are interpreted by ØMQ as a single continous stream

+of data where ØMQ messages are not necessarily aligned with PGM datagram

+==========

+
+NAME
+----
+zmq_pgm - 0MQ reliable multicast transport using PGM
+
+
+SYNOPSIS
+--------
+PGM (Pragmatic General Multicast) is a protocol for reliable multicast
+transport of data over IP networks.
+
+
+DESCRIPTION
+-----------
+0MQ implements two variants of PGM, the standard protocol where PGM datagrams
+are layered directly on top of IP datagrams as defined by RFC 3208 (the 'pgm'
+transport) and "Encapsulated PGM" where PGM datagrams are encapsulated inside
+UDP datagrams (the 'epgm' transport).
+
+The 'pgm' and 'epgm' transports can only be used with the 'ZMQ_PUB' and
+'ZMQ_SUB' socket types.
+
+Further, PGM sockets are rate limited by default and incur a performance
+penalty when used over a loopback interface. For details, refer to the
+'ZMQ_RATE', 'ZMQ_RECOVERY_IVL' and 'ZMQ_MCAST_LOOP' options documented in
+linkzmq:zmq_setsockopt[3].
+
+CAUTION: The 'pgm' transport implementation requires access to raw IP sockets.
+Additional privileges may be required on some operating systems for this
+operation. Applications not requiring direct interoperability with other PGM
+implementations are encouraged to use the 'epgm' transport instead which does
+not require any special privileges.
+
+
+ADDRESSING
+----------
+A 0MQ address string consists of two parts as follows:
+'transport'`://`'endpoint'. The 'transport' part specifies the underlying
+transport protocol to use. For the standard PGM protocol, 'transport' shall be
+set to `pgm`. For the "Encapsulated PGM" protocol 'transport' shall be set to
+`epgm`. The meaning of the 'endpoint' part for both the 'pgm' and 'epgm'
+transport is defined below.
+
+
+Connecting a socket
+~~~~~~~~~~~~~~~~~~~
+When connecting a socket to a peer address using _zmq_connect()_ with the 'pgm'
+or 'epgm' transport, the 'endpoint' shall be interpreted as an 'interface'
+followed by a semicolon, followed by a 'multicast address', followed by a colon
+and a port number.
+
+An 'interface' may be specified by either of the following:
+
+* The interface name as defined by the operating system.
+* The primary IPv4 address assigned to the interface, in it's numeric
+  representation.
+
+NOTE: Interface names are not standardised in any way and should be assumed to
+be arbitrary and platform dependent. On Win32 platforms no short interface
+names exist, thus only the primary IPv4 address may be used to specify an
+'interface'.
+
+A 'multicast address' is specified by an IPv4 multicast address in it's numeric
+representation.
+
+
+WIRE FORMAT
+-----------
+Consecutive PGM datagrams are interpreted by 0MQ as a single continous stream
+of data where 0MQ messages are not necessarily aligned with PGM datagram
+boundaries and a single 0MQ message may span several PGM datagrams. This stream
+of data consists of 0MQ messages encapsulated in 'frames' as described in
+linkzmq:zmq_tcp[7].
+
+
+PGM datagram payload
+~~~~~~~~~~~~~~~~~~~~
+The following ABNF grammar represents the payload of a single PGM datagram as
+used by 0MQ:
+
+....
+datagram               = (offset data)
+offset                 = 2OCTET
+data                   = *OCTET
+....
+
+In order for late joining consumers to be able to identify message boundaries,
+each PGM datagram payload starts with a 16-bit unsigned integer in network byte
+order specifying either the offset of the first message 'frame' in the datagram
+or containing the value `0xFFFF` if the datagram contains solely an
+intermediate part of a larger message.
+
+The following diagram illustrates the layout of a single PGM datagram payload:
+
+....
++------------------+----------------------+
+| offset (16 bits) |         data         |
++------------------+----------------------+
+....
+
+The following diagram further illustrates how three example 0MQ frames are laid
+out in consecutive PGM datagram payloads:
+
+....
+First datagram payload
++--------------+-------------+---------------------+
+| Frame offset |   Frame 1   |   Frame 2, part 1   |
+|    0x0000    | (Message 1) | (Message 2, part 1) |
++--------------+-------------+---------------------+
+
+Second datagram payload
++--------------+---------------------+
+| Frame offset |   Frame 2, part 2   |
+| 0xFFFF       | (Message 2, part 2) |
++--------------+---------------------+
+
+Third datagram payload
++--------------+----------------------------+-------------+
+| Frame offset |   Frame 2, final 8 bytes   |   Frame 3   |
+| 0x0008       | (Message 2, final 8 bytes) | (Message 3) |
++--------------+----------------------------+-------------+
+....

+.SH "NAME"
+zmq_getsockopt \- get 0MQ socket options
+.SH "SYNOPSIS"
+.sp
+\fBint zmq_getsockopt (void \fR\fB\fI*socket\fR\fR\fB, int \fR\fB\fIoption_name\fR\fR\fB, void \fR\fB\fI*option_value\fR\fR\fB, size_t \fR\fB\fI*option_len\fR\fR\fB);\fR
+.SH "DESCRIPTION"
+.sp
+The \fIzmq_getsockopt()\fR function shall retrieve the value for the option specified by the \fIoption_name\fR argument for the 0MQ socket pointed to by the \fIsocket\fR argument, and store it in the buffer pointed to by the \fIoption_value\fR argument\&. The \fIoption_len\fR argument is the size in bytes of the buffer pointed to by \fIoption_value\fR; upon successful completion \fIzmq_getsockopt()\fR shall modify the \fIoption_value\fR argument to indicate the actual size of the option value stored in the buffer\&.
+.sp
+The following options can be retrieved with the \fIzmq_getsockopt()\fR function:
+.SS "ZMQ_RCVMORE: More message parts to follow"
+.sp
+The \fIZMQ_RCVMORE\fR option shall return a boolean value indicating if the multi\-part message currently being read from the specified \fIsocket\fR has more message parts to follow\&. If there are no message parts to follow or if the message currently being read is not a multi\-part message a value of zero shall be returned\&. Otherwise, a value of 1 shall be returned\&.
+.sp
+Refer to \fBzmq_send\fR(3) and \fBzmq_recv\fR(3) for a detailed description of sending/receiving multi\-part messages\&.

+.sp
+The \fIZMQ_HWM\fR option shall retrieve the high water mark for the specified \fIsocket\fR\&. The high water mark is a hard limit on the maximum number of outstanding messages 0MQ shall queue in memory for any single peer that the specified \fIsocket\fR is communicating with\&.
+.sp
+If this limit has been reached the socket shall enter an exceptional state and depending on the socket type, 0MQ shall take appropriate action such as blocking or dropping sent messages\&. Refer to the individual socket descriptions in \fBzmq_socket\fR(3) for details on the exact action taken for each socket type\&.
+.sp
+The default \fIZMQ_HWM\fR value of zero means "no limit"\&.

A socket which has \fIZMQ_SWAP\fR set to a non\-zero value may exceed it\(cqs high water mark; in this case outstanding messages shall be offloaded to storage on disk rather than held in memory\&.

+.sp
+The \fIZMQ_AFFINITY\fR option shall retrieve the I/O thread affinity for newly created connections on the specified \fIsocket\fR\&.
+.sp
+Affinity determines which threads from the 0MQ I/O thread pool associated with the socket\(cqs \fIcontext\fR shall handle newly created connections\&. A value of zero specifies no affinity, meaning that work shall be distributed fairly among all 0MQ I/O threads in the thread pool\&. For non\-zero values, the lowest bit corresponds to thread 1, second lowest bit to thread 2 and so on\&. For example, a value of 3 specifies that subsequent connections on \fIsocket\fR shall be handled exclusively by I/O threads 1 and 2\&.
+.sp
+See also \fBzmq_init\fR(3) for details on allocating the number of I/O threads for a specific \fIcontext\fR\&.

+The \fIZMQ_IDENTITY\fR option shall retrieve the identity of the specified \fIsocket\fR\&. Socket identity determines if existing 0MQ infastructure (\fImessage queues\fR, \fIforwarding devices\fR) shall be identified with a specific application and persist across multiple runs of the application\&.
+.sp
+If the socket has no identity, each run of an application is completely separate from other runs\&. However, with identity set the socket shall re\-use any existing 0MQ infrastructure configured by the previous run(s)\&. Thus the application may receive messages that were sent in the meantime, \fImessage queue\fR limits shall be shared with previous run(s) and so on\&.
+.sp
+Identity can be at least one byte and at most 255 bytes long\&. Identities starting with binary zero are reserved for use by 0MQ infrastructure\&.

A value of zero indicates that the loopback functionality is disabled, while the default value of 1 indicates that the loopback functionality is enabled\&. Leaving multicast loopback enabled when it is not required can have a negative impact on performance\&. Where possible, disable \fIZMQ_MCAST_LOOP\fR in production environments\&.

+argument. The <em>option_len</em> argument is the size in bytes of the buffer pointed

+to by <em>option_value</em>; upon successful completion <em>zmq_getsockopt()</em> shall

+modify the <em>option_value</em> argument to indicate the actual size of the option

+value stored in the buffer.</p></div>

+zmq_getsockopt(3)
+=================
+
+
+NAME
+----
+
+zmq_getsockopt - get 0MQ socket options
+
+
+SYNOPSIS
+--------
+*int zmq_getsockopt (void '*socket', int 'option_name', void '*option_value', size_t '*option_len');*
+
+
+DESCRIPTION
+-----------
+The _zmq_getsockopt()_ function shall retrieve the value for the option
+specified by the 'option_name' argument for the 0MQ socket pointed to by the
+'socket' argument, and store it in the buffer pointed to by the 'option_value'
+argument. The 'option_len' argument is the size in bytes of the buffer pointed
+to by 'option_value'; upon successful completion _zmq_getsockopt()_ shall
+modify the 'option_value' argument to indicate the actual size of the option
+value stored in the buffer.
+
+The following options can be retrieved with the _zmq_getsockopt()_ function:
+
+
+ZMQ_RCVMORE: More message parts to follow
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The 'ZMQ_RCVMORE' option shall return a boolean value indicating if the
+multi-part message currently being read from the specified 'socket' has more
+message parts to follow. If there are no message parts to follow or if the
+message currently being read is not a multi-part message a value of zero shall
+be returned. Otherwise, a value of 1 shall be returned.
+
+Refer to linkzmq:zmq_send[3] and linkzmq:zmq_recv[3] for a detailed description
+of sending/receiving multi-part messages.
+
+[horizontal]
+Option value type:: int64_t
+Option value unit:: boolean
+Default value:: N/A
+Applicable socket types:: all
+
+
+ZMQ_HWM: Retrieve high water mark
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The 'ZMQ_HWM' option shall retrieve the high water mark for the specified
+'socket'.  The high water mark is a hard limit on the maximum number of
+outstanding messages 0MQ shall queue in memory for any single peer that the
+specified 'socket' is communicating with.
+
+If this limit has been reached the socket shall enter an exceptional state and
+depending on the socket type, 0MQ shall take appropriate action such as
+blocking or dropping sent messages. Refer to the individual socket descriptions
+in linkzmq:zmq_socket[3] for details on the exact action taken for each socket
+type.
+
+The default 'ZMQ_HWM' value of zero means "no limit".
+
+[horizontal]
+Option value type:: int64_t
+Option value unit:: messages
+Default value:: 0
+Applicable socket types:: all
+
+
+ZMQ_SWAP: Retrieve disk offload size
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The 'ZMQ_SWAP' option shall retrieve the disk offload (swap) size for the
+specified 'socket'. A socket which has 'ZMQ_SWAP' set to a non-zero value may
+exceed it's high water mark; in this case outstanding messages shall be
+offloaded to storage on disk rather than held in memory.
+
+The value of 'ZMQ_SWAP' defines the maximum size of the swap space in bytes.
+
+[horizontal]
+Option value type:: int64_t
+Option value unit:: bytes
+Default value:: 0
+Applicable socket types:: all
+
+
+ZMQ_AFFINITY: Retrieve I/O thread affinity
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The 'ZMQ_AFFINITY' option shall retrieve the I/O thread affinity for newly
+created connections on the specified 'socket'.
+
+Affinity determines which threads from the 0MQ I/O thread pool associated with
+the socket's _context_ shall handle newly created connections.  A value of zero
+specifies no affinity, meaning that work shall be distributed fairly among all
+0MQ I/O threads in the thread pool. For non-zero values, the lowest bit
+corresponds to thread 1, second lowest bit to thread 2 and so on.  For example,
+a value of 3 specifies that subsequent connections on 'socket' shall be handled
+exclusively by I/O threads 1 and 2.
+
+See also linkzmq:zmq_init[3] for details on allocating the number of I/O
+threads for a specific _context_.
+
+[horizontal]
+Option value type:: int64_t
+Option value unit:: N/A (bitmap)
+Default value:: 0
+Applicable socket types:: N/A
+
+
+ZMQ_IDENTITY: Retrieve socket identity
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The 'ZMQ_IDENTITY' option shall retrieve the identity of the specified
+'socket'. Socket identity determines if existing 0MQ infastructure (_message
+queues_, _forwarding devices_) shall be identified with a specific application
+and persist across multiple runs of the application.
+
+If the socket has no identity, each run of an application is completely
+separate from other runs. However, with identity set the socket shall re-use
+any existing 0MQ infrastructure configured by the previous run(s). Thus the
+application may receive messages that were sent in the meantime, _message
+queue_ limits shall be shared with previous run(s) and so on.
+
+Identity can be at least one byte and at most 255 bytes long. Identities
+starting with binary zero are reserved for use by 0MQ infrastructure.
+
+[horizontal]
+Option value type:: binary data
+Option value unit:: N/A
+Default value:: NULL
+Applicable socket types:: all
+
+
+ZMQ_RATE: Retrieve multicast data rate
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The 'ZMQ_RATE' option shall retrieve the maximum send or receive data rate for
+multicast transports using the specified 'socket'.
+
+[horizontal]
+Option value type:: uint64_t
+Option value unit:: kilobits per second
+Default value:: 100
+Applicable socket types:: all, when using multicast transports
+
+
+ZMQ_RECOVERY_IVL: Get multicast recovery interval
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The 'ZMQ_RECOVERY_IVL' option shall retrieve the recovery interval for
+multicast transports using the specified 'socket'.  The recovery interval
+determines the maximum time in seconds that a receiver can be absent from a
+multicast group before unrecoverable data loss will occur.
+
+[horizontal]
+Option value type:: uint64_t
+Option value unit:: seconds
+Default value:: 10
+Applicable socket types:: all, when using multicast transports
+
+
+ZMQ_MCAST_LOOP: Control multicast loopback
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The 'ZMQ_MCAST_LOOP' option controls whether data sent via multicast
+transports can also be received by the sending host via loopback.  A value of
+zero indicates that the loopback functionality is disabled, while the default
+value of 1 indicates that the loopback functionality is enabled.  Leaving
+multicast loopback enabled when it is not required can have a negative impact
+on performance. Where possible, disable 'ZMQ_MCAST_LOOP' in production
+environments.
+
+[horizontal]
+Option value type:: uint64_t
+Option value unit:: boolean
+Default value:: 1
+Applicable socket types:: all, when using multicast transports
+
+
+ZMQ_SNDBUF: Retrieve kernel transmit buffer size
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The 'ZMQ_SNDBUF' option shall retrieve the underlying kernel transmit buffer
+size for the specified 'socket'. A value of zero means that the OS default is
+in effect. For details refer to your operating system documentation for the
+'SO_SNDBUF' socket option.
+
+[horizontal]
+Option value type:: uint64_t
+Option value unit:: bytes
+Default value:: 0
+Applicable socket types:: all
+
+
+ZMQ_RCVBUF: Retrieve kernel receive buffer size
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The 'ZMQ_RCVBUF' option shall retrieve the underlying kernel receive buffer
+size for the specified 'socket'. A value of zero means that the OS default is
+in effect. For details refer to your operating system documentation for the
+'SO_RCVBUF' socket option.
+
+[horizontal]
+Option value type:: uint64_t
+Option value unit:: bytes
+Default value:: 0
+Applicable socket types:: all
+
+
+RETURN VALUE
+------------
+The _zmq_getsockopt()_ function shall return zero if successful. Otherwise it
+shall return `-1` and set 'errno' to one of the values defined below.
+
+
+ERRORS
+------
+*EINVAL*::
+The requested option _option_name_ is unknown, or the requested _option_len_ or
+_option_value_ is invalid, or the size of the buffer pointed to by
+_option_value_, as specified by _option_len_, is insufficient for storing the
+option value.
+*ETERM*::
+The 0MQ 'context' associated with the specified 'socket' was terminated.

+NAME
+----
+zmq_init - initialise 0MQ context
+
+
+SYNOPSIS
+--------
+*void *zmq_init (int 'io_threads');*
+
+
+DESCRIPTION
+-----------
+The _zmq_init()_ function initialises a 0MQ 'context'.
+
+The 'io_threads' argument specifies the size of the 0MQ thread pool to handle
+I/O operations. If your application is using only the 'inproc' transport for
+messaging you may set this to zero, otherwise set it to at least one.
+
+
+RETURN VALUE
+------------
+The _zmq_init()_ function shall return an opaque handle to the initialised
+'context' if successful. Otherwise it shall return NULL and set 'errno' to one
+of the values defined below.
+
+
+ERRORS
+------
+*EINVAL*::
+An invalid number of 'io_threads' was requested.

+.SH "NAME"
+zmq_inproc \- 0MQ local in\-process (inter\-thread) communication transport
+.SH "SYNOPSIS"
+.sp
+The in\-process transport passes messages via memory directly between threads sharing a single 0MQ \fIcontext\fR\&.
+.if n \{\
+.sp
+.\}
+.RS 4
+.it 1 an-trap
+.nr an-no-space-flag 1
+.nr an-break-flag 1
+.br
+.ps +1
+\fBNote\fR
+.ps -1
+.br
+.sp
+No I/O threads are involved in passing messages using the \fIinproc\fR transport\&. Therefore, if you are using a 0MQ \fIcontext\fR for in\-process messaging only you can initialise the \fIcontext\fR with zero I/O threads\&. See \fBzmq_init\fR(3) for details\&.
+.sp .5v
+.RE
+.SH "ADDRESSING"
+.sp
+A 0MQ address string consists of two parts as follows: \fItransport\fR://\fIendpoint\fR\&. The \fItransport\fR part specifies the underlying transport protocol to use, and for the in\-process transport shall be set to inproc\&. The meaning of the \fIendpoint\fR part for the in\-process transport is defined below\&.
+.SS "Assigning a local address to a socket"
+.sp
+When assigning a local address to a \fIsocket\fR using \fIzmq_bind()\fR with the \fIinproc\fR transport, the \fIendpoint\fR shall be interpreted as an arbitrary string identifying the \fIname\fR to create\&. The \fIname\fR must be unique within the 0MQ \fIcontext\fR associated with the \fIsocket\fR and may be up to 256 characters in length\&. No other restrictions are placed on the format of the \fIname\fR\&.
+.SS "Connecting a socket"
+.sp
+When connecting a \fIsocket\fR to a peer address using \fIzmq_connect()\fR with the \fIinproc\fR transport, the \fIendpoint\fR shall be interpreted as an arbitrary string identifying the \fIname\fR to connect to\&. The \fIname\fR must have been previously created by assigning it to at least one \fIsocket\fR within the same 0MQ \fIcontext\fR as the \fIsocket\fR being connected\&.

+NAME
+----
+zmq_inproc - 0MQ local in-process (inter-thread) communication transport
+
+
+SYNOPSIS
+--------
+The in-process transport passes messages via memory directly between threads
+sharing a single 0MQ 'context'.
+
+NOTE: No I/O threads are involved in passing messages using the 'inproc'
+transport. Therefore, if you are using a 0MQ 'context' for in-process messaging
+only you can initialise the 'context' with zero I/O threads. See
+linkzmq:zmq_init[3] for details.
+
+
+ADDRESSING
+----------
+A 0MQ address string consists of two parts as follows:
+'transport'`://`'endpoint'. The 'transport' part specifies the underlying
+transport protocol to use, and for the in-process transport shall be set to
+`inproc`.  The meaning of the 'endpoint' part for the in-process transport is
+defined below.
+
+
+Assigning a local address to a socket
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+When assigning a local address to a 'socket' using _zmq_bind()_ with the
+'inproc' transport, the 'endpoint' shall be interpreted as an arbitrary string
+identifying the 'name' to create. The 'name' must be unique within the 0MQ
+'context' associated with the 'socket' and may be up to 256 characters in
+length.  No other restrictions are placed on the format of the 'name'.
+
+
+Connecting a socket
+~~~~~~~~~~~~~~~~~~~
+When connecting a 'socket' to a peer address using _zmq_connect()_ with the
+'inproc' transport, the 'endpoint' shall be interpreted as an arbitrary string
+identifying the 'name' to connect to.  The 'name' must have been previously
+created by assigning it to at least one 'socket' within the same 0MQ 'context'
+as the 'socket' being connected.

+zmq_ipc \- 0MQ local inter\-process communication transport
+.SH "SYNOPSIS"

+The inter\-process transport passes messages between local processes using a system\-dependent IPC mechanism\&.

+The inter\-process transport is currently only implemented on operating systems that provide UNIX domain sockets\&.

+.RE
+.SH "ADDRESSING"
+.sp
+A 0MQ address string consists of two parts as follows: \fItransport\fR://\fIendpoint\fR\&. The \fItransport\fR part specifies the underlying transport protocol to use, and for the inter\-process transport shall be set to ipc\&. The meaning of the \fIendpoint\fR part for the inter\-process transport is defined below\&.
+.SS "Assigning a local address to a socket"
+.sp
+When assigning a local address to a \fIsocket\fR using \fIzmq_bind()\fR with the \fIipc\fR transport, the \fIendpoint\fR shall be interpreted as an arbitrary string identifying the \fIpathname\fR to create\&. The \fIpathname\fR must be unique within the operating system namespace used by the \fIipc\fR implementation, and must fulfill any restrictions placed by the operating system on the format and length of a \fIpathname\fR\&.
+.SS "Connecting a socket"
+.sp
+When connecting a \fIsocket\fR to a peer address using \fIzmq_connect()\fR with the \fIipc\fR transport, the \fIendpoint\fR shall be interpreted as an arbitrary string identifying the \fIpathname\fR to connect to\&. The \fIpathname\fR must have been previously created within the operating system namespace by assigning it to a \fIsocket\fR with \fIzmq_bind()\fR\&.

+==========

+
+NAME
+----
+zmq_ipc - 0MQ local inter-process communication transport
+
+
+SYNOPSIS
+--------
+The inter-process transport passes messages between local processes using a
+system-dependent IPC mechanism.
+
+NOTE: The inter-process transport is currently only implemented on operating
+systems that provide UNIX domain sockets.
+
+
+ADDRESSING
+----------
+A 0MQ address string consists of two parts as follows:
+'transport'`://`'endpoint'. The 'transport' part specifies the underlying
+transport protocol to use, and for the inter-process transport shall be set to
+`ipc`.  The meaning of the 'endpoint' part for the inter-process transport is
+defined below.
+
+
+Assigning a local address to a socket
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+When assigning a local address to a 'socket' using _zmq_bind()_ with the 'ipc'
+transport, the 'endpoint' shall be interpreted as an arbitrary string
+identifying the 'pathname' to create. The 'pathname' must be unique within the
+operating system namespace used by the 'ipc' implementation, and must fulfill
+any restrictions placed by the operating system on the format and length of a
+'pathname'.
+
+Connecting a socket
+~~~~~~~~~~~~~~~~~~~
+When connecting a 'socket' to a peer address using _zmq_connect()_ with the
+'ipc' transport, the 'endpoint' shall be interpreted as an arbitrary string
+identifying the 'pathname' to connect to.  The 'pathname' must have been
+previously created within the operating system namespace by assigning it to a
+'socket' with _zmq_bind()_.
+
+
+WIRE FORMAT
+-----------
+Not applicable.
+
+
+EXAMPLES
+--------
+.Assigning a local address to a socket
+----
+/* Assign the pathname "/tmp/feeds/0" */
+rc = zmq_bind(socket, "ipc:///tmp/feeds/0");
+assert (rc == 0);
+----
+
+.Connecting a socket
+----
+/* Connect to the pathname "/tmp/feeds/0" */
+rc = zmq_connect(socket, "ipc:///tmp/feeds/0");
+assert (rc == 0);

+.SH "SYNOPSIS"
+.sp
+\fBint zmq_msg_close (zmq_msg_t \fR\fB\fI*msg\fR\fR\fB);\fR
+.SH "DESCRIPTION"
+.sp
+The \fIzmq_msg_close()\fR function shall inform the 0MQ infrastructure that any resources associated with the message object referenced by \fImsg\fR are no longer required and may be released\&. Actual release of resources associated with the message object shall be postponed by 0MQ until all users of the message or underlying data buffer have indicated it is no longer required\&.
+.sp
+Applications should ensure that \fIzmq_msg_close()\fR is called once a message is no longer required, otherwise memory leaks may occur\&.

+.SH "RETURN VALUE"
+.sp
+The \fIzmq_msg_close()\fR function shall return zero if successful\&. Otherwise it shall return \-1 and set \fIerrno\fR to one of the values defined below\&.

+.SH "DESCRIPTION"
+.sp
+The \fIzmq_msg_copy()\fR function shall copy the message object referenced by \fIsrc\fR to the message object referenced by \fIdest\fR\&. The original content of \fIdest\fR, if any, shall be released\&.

+\fBCaution\fR
+.ps -1
+.br
+.sp
+The implementation may choose not to physically copy the message content, rather to share the underlying buffer between \fIsrc\fR and \fIdest\fR\&. Avoid modifying message content after a message has been copied with \fIzmq_msg_copy()\fR, doing so can result in undefined behaviour\&. If what you need is an actual hard copy, allocate a new message using \fIzmq_msg_init_size()\fR and copy the message content using \fImemcpy()\fR\&.

+zmq_msg_copy(3)
+===============
+
+
+NAME
+----
+zmq_msg_copy - copy content of a message to another message
+
+
+SYNOPSIS
+--------
+*int zmq_msg_copy (zmq_msg_t '*dest', zmq_msg_t '*src');*
+
+
+DESCRIPTION
+-----------
+The _zmq_msg_copy()_ function shall copy the message object referenced by 'src'
+to the message object referenced by 'dest'. The original content of 'dest', if
+any, shall be released.
+
+CAUTION: The implementation may choose not to physically copy the message
+content, rather to share the underlying buffer between 'src' and 'dest'. Avoid
+modifying message content after a message has been copied with
+_zmq_msg_copy()_, doing so can result in undefined behaviour. If what you need
+is an actual hard copy, allocate a new message using _zmq_msg_init_size()_ and
+copy the message content using _memcpy()_.
+
+CAUTION: Never access 'zmq_msg_t' members directly, instead always use the
+_zmq_msg_ family of functions.
+
+
+RETURN VALUE
+------------
+The _zmq_msg_copy()_ function shall return zero if successful. Otherwise it
+shall return `-1` and set 'errno' to one of the values defined below.
+
+
+ERRORS
+------
+No errors are defined.

+
+
+SYNOPSIS
+--------
+*int zmq_msg_init (zmq_msg_t '*msg');*
+
+
+DESCRIPTION
+-----------
+The _zmq_msg_init()_ function shall initialise the message object referenced by
+'msg' to represent an empty message.  This function is most useful when called
+before receiving a message with _zmq_recv()_.
+
+CAUTION: Never access 'zmq_msg_t' members directly, instead always use the
+_zmq_msg_ family of functions.
+
+CAUTION: The functions _zmq_msg_init()_, _zmq_msg_init_data()_ and
+_zmq_msg_init_size()_ are mutually exclusive. Never initialize the same
+'zmq_msg_t' twice.
+
+
+RETURN VALUE
+------------
+The _zmq_msg_init()_ function shall return zero if successful. Otherwise it
+shall return `-1` and set 'errno' to one of the values defined below.
+
+
+ERRORS
+------
+No errors are defined.
+
+
+EXAMPLE
+-------
+.Receiving a message from a socket
+----
+zmq_msg_t msg;
+rc = zmq_msg_init (&msg);
+assert (rc == 0);
+rc = zmq_recv (socket, &msg, 0);

+NAME
+----
+zmq_msg_init_data - initialise 0MQ message from a supplied buffer
+
+
+SYNOPSIS
+--------
+*typedef void (zmq_free_fn) (void '*data', void '*hint');*
+
+*int zmq_msg_init_data (zmq_msg_t '*msg', void '*data', size_t 'size', zmq_free_fn '*ffn', void '*hint');*
+
+
+DESCRIPTION
+-----------
+The _zmq_msg_init_data()_ function shall initialise the message object
+referenced by 'msg' to represent the content referenced by the buffer located
+at address 'data', 'size' bytes long. No copy of 'data' shall be performed and
+0MQ shall take ownership of the supplied buffer.
+
+If provided, the deallocation function 'ffn' shall be called once the data
+buffer is no longer required by 0MQ, with the 'data' and 'hint' arguments
+supplied to _zmq_msg_init_data()_.
+
+CAUTION: Never access 'zmq_msg_t' members directly, instead always use the
+_zmq_msg_ family of functions.
+
+CAUTION: The functions _zmq_msg_init()_, _zmq_msg_init_data()_ and
+_zmq_msg_init_size()_ are mutually exclusive. Never initialize the same
+'zmq_msg_t' twice.
+
+
+RETURN VALUE
+------------
+The _zmq_msg_init_data()_ function shall return zero if successful. Otherwise
+it shall return `-1` and set 'errno' to one of the values defined below.
+
+
+ERRORS
+------
+No errors are defined.

+NAME
+----
+zmq_msg_init_size - initialise 0MQ message of a specified size
+
+
+SYNOPSIS
+--------
+*int zmq_msg_init_size (zmq_msg_t '*msg', size_t 'size');*
+
+
+DESCRIPTION
+-----------
+The _zmq_msg_init_size()_ function shall allocate any resources required to
+store a message 'size' bytes long and initialise the message object referenced
+by 'msg' to represent the newly allocated message.
+
+The implementation shall choose whether to store message content on the stack
+(small messages) or on the heap (large messages). For performance reasons
+_zmq_msg_init_size()_ shall not clear the message data.
+
+CAUTION: Never access 'zmq_msg_t' members directly, instead always use the
+_zmq_msg_ family of functions.
+
+CAUTION: The functions _zmq_msg_init()_, _zmq_msg_init_data()_ and
+_zmq_msg_init_size()_ are mutually exclusive. Never initialize the same
+'zmq_msg_t' twice.
+
+
+RETURN VALUE
+------------
+The _zmq_msg_init_size()_ function shall return zero if successful. Otherwise
+it shall return `-1` and set 'errno' to one of the values defined below.
+
+
+ERRORS
+------

+.SH "NAME"
+zmq_pgm \- 0MQ reliable multicast transport using PGM
+.SH "SYNOPSIS"
+.sp
+PGM (Pragmatic General Multicast) is a protocol for reliable multicast transport of data over IP networks\&.
+.SH "DESCRIPTION"
+.sp
+0MQ implements two variants of PGM, the standard protocol where PGM datagrams are layered directly on top of IP datagrams as defined by RFC 3208 (the \fIpgm\fR transport) and "Encapsulated PGM" where PGM datagrams are encapsulated inside UDP datagrams (the \fIepgm\fR transport)\&.
+.sp
+The \fIpgm\fR and \fIepgm\fR transports can only be used with the \fIZMQ_PUB\fR and \fIZMQ_SUB\fR socket types\&.
+.sp
+Further, PGM sockets are rate limited by default and incur a performance penalty when used over a loopback interface\&. For details, refer to the \fIZMQ_RATE\fR, \fIZMQ_RECOVERY_IVL\fR and \fIZMQ_MCAST_LOOP\fR options documented in \fBzmq_setsockopt\fR(3)\&.

+.br
+.ps +1
+\fBCaution\fR
+.ps -1
+.br
+.sp
+The \fIpgm\fR transport implementation requires access to raw IP sockets\&. Additional privileges may be required on some operating systems for this operation\&. Applications not requiring direct interoperability with other PGM implementations are encouraged to use the \fIepgm\fR transport instead which does not require any special privileges\&.
+.sp .5v
+.RE
+.SH "ADDRESSING"
+.sp
+A 0MQ address string consists of two parts as follows: \fItransport\fR://\fIendpoint\fR\&. The \fItransport\fR part specifies the underlying transport protocol to use\&. For the standard PGM protocol, \fItransport\fR shall be set to pgm\&. For the "Encapsulated PGM" protocol \fItransport\fR shall be set to epgm\&. The meaning of the \fIendpoint\fR part for both the \fIpgm\fR and \fIepgm\fR transport is defined below\&.
+.SS "Connecting a socket"
+.sp
+When connecting a socket to a peer address using \fIzmq_connect()\fR with the \fIpgm\fR or \fIepgm\fR transport, the \fIendpoint\fR shall be interpreted as an \fIinterface\fR followed by a semicolon, followed by a \fImulticast address\fR, followed by a colon and a port number\&.
+.sp
+An \fIinterface\fR may be specified by either of the following:
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+The interface name as defined by the operating system\&.
+.RE
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+The primary IPv4 address assigned to the interface, in it\(cqs numeric representation\&.
+.RE
+.if n \{\
+.sp
+.\}
+.RS 4
+.it 1 an-trap
+.nr an-no-space-flag 1
+.nr an-break-flag 1
+.br
+.ps +1
+\fBNote\fR
+.ps -1
+.br
+.sp
+Interface names are not standardised in any way and should be assumed to be arbitrary and platform dependent\&. On Win32 platforms no short interface names exist, thus only the primary IPv4 address may be used to specify an \fIinterface\fR\&.
+.sp .5v
+.RE
+.sp
+A \fImulticast address\fR is specified by an IPv4 multicast address in it\(cqs numeric representation\&.
+.SH "WIRE FORMAT"
+.sp
+Consecutive PGM datagrams are interpreted by 0MQ as a single continous stream of data where 0MQ messages are not necessarily aligned with PGM datagram boundaries and a single 0MQ message may span several PGM datagrams\&. This stream of data consists of 0MQ messages encapsulated in \fIframes\fR as described in \fBzmq_tcp\fR(7)\&.
+.SS "PGM datagram payload"
+.sp
+The following ABNF grammar represents the payload of a single PGM datagram as used by 0MQ:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+datagram               = (offset data)
+offset                 = 2OCTET
+data                   = *OCTET
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+In order for late joining consumers to be able to identify message boundaries, each PGM datagram payload starts with a 16\-bit unsigned integer in network byte order specifying either the offset of the first message \fIframe\fR in the datagram or containing the value 0xFFFF if the datagram contains solely an intermediate part of a larger message\&.
+.sp
+The following diagram illustrates the layout of a single PGM datagram payload:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
++\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+

++\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+The following diagram further illustrates how three example 0MQ frames are laid out in consecutive PGM datagram payloads:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+First datagram payload
++\-\-\-\-\-\-\-\-\-\-\-\-\-\-+\-\-\-\-\-\-\-\-\-\-\-\-\-+\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+

++\-\-\-\-\-\-\-\-\-\-\-\-\-\-+\-\-\-\-\-\-\-\-\-\-\-\-\-+\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+
+
+Second datagram payload
++\-\-\-\-\-\-\-\-\-\-\-\-\-\-+\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+
+| Frame offset |   Frame 2, part 2   |
+| 0xFFFF       | (Message 2, part 2) |
++\-\-\-\-\-\-\-\-\-\-\-\-\-\-+\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+
+
+Third datagram payload

+NAME
+----
+zmq_pgm - 0MQ reliable multicast transport using PGM
+
+
+SYNOPSIS
+--------
+PGM (Pragmatic General Multicast) is a protocol for reliable multicast
+transport of data over IP networks.
+
+
+DESCRIPTION
+-----------
+0MQ implements two variants of PGM, the standard protocol where PGM datagrams
+are layered directly on top of IP datagrams as defined by RFC 3208 (the 'pgm'
+transport) and "Encapsulated PGM" where PGM datagrams are encapsulated inside
+UDP datagrams (the 'epgm' transport).
+
+The 'pgm' and 'epgm' transports can only be used with the 'ZMQ_PUB' and
+'ZMQ_SUB' socket types.
+
+Further, PGM sockets are rate limited by default and incur a performance
+penalty when used over a loopback interface. For details, refer to the
+'ZMQ_RATE', 'ZMQ_RECOVERY_IVL' and 'ZMQ_MCAST_LOOP' options documented in
+linkzmq:zmq_setsockopt[3].
+
+CAUTION: The 'pgm' transport implementation requires access to raw IP sockets.
+Additional privileges may be required on some operating systems for this
+operation. Applications not requiring direct interoperability with other PGM
+implementations are encouraged to use the 'epgm' transport instead which does
+not require any special privileges.
+
+
+ADDRESSING
+----------
+A 0MQ address string consists of two parts as follows:
+'transport'`://`'endpoint'. The 'transport' part specifies the underlying
+transport protocol to use. For the standard PGM protocol, 'transport' shall be
+set to `pgm`. For the "Encapsulated PGM" protocol 'transport' shall be set to
+`epgm`. The meaning of the 'endpoint' part for both the 'pgm' and 'epgm'
+transport is defined below.
+
+
+Connecting a socket
+~~~~~~~~~~~~~~~~~~~
+When connecting a socket to a peer address using _zmq_connect()_ with the 'pgm'
+or 'epgm' transport, the 'endpoint' shall be interpreted as an 'interface'
+followed by a semicolon, followed by a 'multicast address', followed by a colon
+and a port number.
+
+An 'interface' may be specified by either of the following:
+
+* The interface name as defined by the operating system.
+* The primary IPv4 address assigned to the interface, in it's numeric
+  representation.
+
+NOTE: Interface names are not standardised in any way and should be assumed to
+be arbitrary and platform dependent. On Win32 platforms no short interface
+names exist, thus only the primary IPv4 address may be used to specify an
+'interface'.
+
+A 'multicast address' is specified by an IPv4 multicast address in it's numeric
+representation.
+
+
+WIRE FORMAT
+-----------
+Consecutive PGM datagrams are interpreted by 0MQ as a single continous stream
+of data where 0MQ messages are not necessarily aligned with PGM datagram
+boundaries and a single 0MQ message may span several PGM datagrams. This stream
+of data consists of 0MQ messages encapsulated in 'frames' as described in
+linkzmq:zmq_tcp[7].
+
+
+PGM datagram payload
+~~~~~~~~~~~~~~~~~~~~
+The following ABNF grammar represents the payload of a single PGM datagram as
+used by 0MQ:
+
+....
+datagram               = (offset data)
+offset                 = 2OCTET
+data                   = *OCTET
+....
+
+In order for late joining consumers to be able to identify message boundaries,
+each PGM datagram payload starts with a 16-bit unsigned integer in network byte
+order specifying either the offset of the first message 'frame' in the datagram
+or containing the value `0xFFFF` if the datagram contains solely an
+intermediate part of a larger message.
+
+The following diagram illustrates the layout of a single PGM datagram payload:
+
+....
++------------------+----------------------+
+| offset (16 bits) |         data         |
++------------------+----------------------+
+....
+
+The following diagram further illustrates how three example 0MQ frames are laid
+out in consecutive PGM datagram payloads:
+
+....
+First datagram payload
++--------------+-------------+---------------------+
+| Frame offset |   Frame 1   |   Frame 2, part 1   |
+|    0x0000    | (Message 1) | (Message 2, part 1) |
++--------------+-------------+---------------------+
+
+Second datagram payload
++--------------+---------------------+
+| Frame offset |   Frame 2, part 2   |
+| 0xFFFF       | (Message 2, part 2) |
++--------------+---------------------+
+
+Third datagram payload
++--------------+----------------------------+-------------+
+| Frame offset |   Frame 2, final 8 bytes   |   Frame 3   |
+| 0x0008       | (Message 2, final 8 bytes) | (Message 3) |
++--------------+----------------------------+-------------+
+....

+.SH "DESCRIPTION"
+.sp
+The \fIzmq_poll()\fR function provides a mechanism for applications to multiplex input/output events in a level\-triggered fashion over a set of sockets\&. Each member of the array pointed to by the \fIitems\fR argument is a \fBzmq_pollitem_t\fR structure\&. The \fInitems\fR argument specifies the number of items in the \fIitems\fR array\&. The \fBzmq_pollitem_t\fR structure is defined as follows:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+typedef struct
+{
+    void \fI*socket\fR;
+    int \fIfd\fR;

+} zmq_pollitem_t;
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+For each \fBzmq_pollitem_t\fR item, \fIzmq_poll()\fR shall examine either the 0MQ socket referenced by \fIsocket\fR \fBor\fR the standard socket specified by the file descriptor \fIfd\fR, for the event(s) specified in \fIevents\fR\&. If both \fIsocket\fR and \fIfd\fR are set in a single \fBzmq_pollitem_t\fR, the 0MQ socket referenced by \fIsocket\fR shall take precedence and the value of \fIfd\fR shall be ignored\&.

+.sp
+For each \fBzmq_pollitem_t\fR item, \fIzmq_poll()\fR shall first clear the \fIrevents\fR member, and then indicate any requested events that have occured by setting the bit corresponding to the event condition in the \fIrevents\fR member\&.
+.sp
+If none of the requested events have occured on any \fBzmq_pollitem_t\fR item, \fIzmq_poll()\fR shall wait up to \fItimeout\fR microseconds for an event to occur on any of the requested items\&. If the value of \fItimeout\fR is 0, \fIzmq_poll()\fR shall return immediately\&. If the value of \fItimeout\fR is \-1, \fIzmq_poll()\fR shall block indefinitely until a requested event has occured on at least one \fBzmq_pollitem_t\fR\&.
+.sp
+The \fIevents\fR and \fIrevents\fR members of \fBzmq_pollitem_t\fR are bitmasks constructed by OR\(cqing a combination of the following event flags:

+\fBZMQ_POLLIN\fR
+.RS 4

+\fIsocket\fR

+\fIPOLLIN\fR
+flag of the
+\fIpoll()\fR
+system call and generally means that at least one byte of data may be read from
+\fIfd\fR
+without blocking\&.
+.RE
+.PP
+\fBZMQ_POLLOUT\fR
+.RS 4
+For 0MQ sockets, at least one message may be sent to the
+\fIsocket\fR
+without blocking\&. For standard sockets this is equivalent to the
+\fIPOLLOUT\fR

+system call and generally means that at least one byte of data may be written to
+\fIfd\fR
+without blocking\&.
+.RE
+.PP
+\fBZMQ_POLLERR\fR
+.RS 4
+For standard sockets, this flag is passed through
+\fIzmq_poll()\fR

+\fIpoll()\fR
+system call and generally means that some sort of error condition is present on the socket specified by
+\fIfd\fR\&. For 0MQ sockets this flag has no effect if set in
+\fIevents\fR, and shall never be returned in

+<div class="sectionbody">

+<div class="paragraph"><p>The <em>zmq_poll()</em> function provides a mechanism for applications to multiplex

+input/output events in a level-triggered fashion over a set of sockets. Each

+member of the array pointed to by the <em>items</em> argument is a <strong>zmq_pollitem_t</strong>

+structure. The <em>nitems</em> argument specifies the number of items in the <em>items</em>

+array. The <strong>zmq_pollitem_t</strong> structure is defined as follows:</p></div>

+<div class="literalblock">

+<div class="content">

+<pre><tt>typedef struct

+{

+    void <em>*socket</em>;

+    int <em>fd</em>;

+    short <em>events</em>;

+    short <em>revents</em>;

+} zmq_pollitem_t;</tt></pre>

+</div></div>

+<div class="paragraph"><p>For each <strong>zmq_pollitem_t</strong> item, <em>zmq_poll()</em> shall examine either the ØMQ

+socket referenced by <em>socket</em> <strong>or</strong> the standard socket specified by the file

+descriptor <em>fd</em>, for the event(s) specified in <em>events</em>. If both <em>socket</em> and

+<em>fd</em> are set in a single <strong>zmq_pollitem_t</strong>, the ØMQ socket referenced by

+<em>socket</em> shall take precedence and the value of <em>fd</em> shall be ignored.</p></div>

+<div class="admonitionblock">

+<table><tr>

+<td class="icon">

+<div class="title">Note</div>

+</td>

+<td class="content">All ØMQ sockets passed to the <em>zmq_poll()</em> function must share the

+same ØMQ <em>context</em> and must belong to the thread calling <em>zmq_poll()</em>.</td>

+</tr></table>

+</div>

+<div class="paragraph"><p>For each <strong>zmq_pollitem_t</strong> item, <em>zmq_poll()</em> shall first clear the <em>revents</em>

+member, and then indicate any requested events that have occured by setting the

+bit corresponding to the event condition in the <em>revents</em> member.</p></div>

+<div class="paragraph"><p>If none of the requested events have occured on any <strong>zmq_pollitem_t</strong> item,

+<em>zmq_poll()</em> shall wait up to <em>timeout</em> microseconds for an event to occur on

+any of the requested items. If the value of <em>timeout</em> is <tt>0</tt>, <em>zmq_poll()</em>

+shall return immediately. If the value of <em>timeout</em> is <tt>-1</tt>, <em>zmq_poll()</em> shall

+block indefinitely until a requested event has occured on at least one

+<strong>zmq_pollitem_t</strong>.</p></div>

+<div class="paragraph"><p>The <em>events</em> and <em>revents</em> members of <strong>zmq_pollitem_t</strong> are bitmasks constructed

+<strong>ZMQ_POLLIN</strong>

+</dt>

+<dd>

+<p>

+For ØMQ sockets, at least one message may be received from the <em>socket</em> without

+blocking. For standard sockets this is equivalent to the <em>POLLIN</em> flag of the

+<em>poll()</em> system call and generally means that at least one byte of data may be

+read from <em>fd</em> without blocking.

+</p>

+</dd>

+<dt class="hdlist1">

+<strong>ZMQ_POLLOUT</strong>

+</dt>

+<dd>

+<p>

+For ØMQ sockets, at least one message may be sent to the <em>socket</em> without

+blocking. For standard sockets this is equivalent to the <em>POLLOUT</em> flag of the

+<em>poll()</em> system call and generally means that at least one byte of data may be

+written to <em>fd</em> without blocking.

+</p>

+</dd>

+<dt class="hdlist1">

+<strong>ZMQ_POLLERR</strong>

+</dt>

+<dd>

+<p>

+For standard sockets, this flag is passed through <em>zmq_poll()</em> to the

+underlying <em>poll()</em> system call and generally means that some sort of error

+condition is present on the socket specified by <em>fd</em>. For ØMQ sockets this flag

+has no effect if set in <em>events</em>, and shall never be returned in <em>revents</em> by

+<em>zmq_poll()</em>.

+zmq_poll(3)
+===========
+
+
+NAME
+----
+zmq_poll - input/output multiplexing
+
+
+SYNOPSIS
+--------
+
+*int zmq_poll (zmq_pollitem_t '*items', int 'nitems', long 'timeout');*
+
+
+DESCRIPTION
+-----------
+The _zmq_poll()_ function provides a mechanism for applications to multiplex
+input/output events in a level-triggered fashion over a set of sockets. Each
+member of the array pointed to by the 'items' argument is a *zmq_pollitem_t*
+structure. The 'nitems' argument specifies the number of items in the 'items'
+array. The *zmq_pollitem_t* structure is defined as follows:
+
+["literal", subs="quotes"]
+typedef struct
+{
+    void '*socket';
+    int 'fd';
+    short 'events';
+    short 'revents';
+} zmq_pollitem_t;
+
+For each *zmq_pollitem_t* item, _zmq_poll()_ shall examine either the 0MQ
+socket referenced by 'socket' *or* the standard socket specified by the file
+descriptor 'fd', for the event(s) specified in 'events'. If both 'socket' and
+'fd' are set in a single *zmq_pollitem_t*, the 0MQ socket referenced by
+'socket' shall take precedence and the value of 'fd' shall be ignored.
+
+NOTE: All 0MQ sockets passed to the _zmq_poll()_ function must share the
+same 0MQ 'context' and must belong to the thread calling _zmq_poll()_.
+
+For each *zmq_pollitem_t* item, _zmq_poll()_ shall first clear the 'revents'
+member, and then indicate any requested events that have occured by setting the
+bit corresponding to the event condition in the 'revents' member.
+
+If none of the requested events have occured on any *zmq_pollitem_t* item,
+_zmq_poll()_ shall wait up to 'timeout' microseconds for an event to occur on
+any of the requested items. If the value of 'timeout' is `0`, _zmq_poll()_
+shall return immediately. If the value of 'timeout' is `-1`, _zmq_poll()_ shall
+block indefinitely until a requested event has occured on at least one
+*zmq_pollitem_t*.
+
+The 'events' and 'revents' members of *zmq_pollitem_t* are bitmasks constructed
+by OR'ing a combination of the following event flags:
+
+*ZMQ_POLLIN*::
+For 0MQ sockets, at least one message may be received from the 'socket' without
+blocking. For standard sockets this is equivalent to the 'POLLIN' flag of the
+_poll()_ system call and generally means that at least one byte of data may be
+read from 'fd' without blocking.
+
+*ZMQ_POLLOUT*::
+For 0MQ sockets, at least one message may be sent to the 'socket' without
+blocking. For standard sockets this is equivalent to the 'POLLOUT' flag of the
+_poll()_ system call and generally means that at least one byte of data may be
+written to 'fd' without blocking.
+
+*ZMQ_POLLERR*::
+For standard sockets, this flag is passed through _zmq_poll()_ to the
+underlying _poll()_ system call and generally means that some sort of error
+condition is present on the socket specified by 'fd'. For 0MQ sockets this flag
+has no effect if set in 'events', and shall never be returned in 'revents' by
+_zmq_poll()_.
+
+NOTE: The _zmq_poll()_ function may be implemented or emulated using operating
+system interfaces other than _poll()_, and as such may be subject to the limits
+of those interfaces in ways not defined in this documentation.
+
+
+RETURN VALUE
+------------
+Upon successful completion, the _zmq_poll()_ function shall return the number
+of *zmq_pollitem_t* structures with events signaled in 'revents' or `0` if no
+events have been signaled. Upon failure, _zmq_poll()_ shall return `-1` and set
+'errno' to one of the values defined below.
+
+IMPORTANT: The _zmq_poll()_ function may return *before* the 'timeout' period
+has expired even if no events have been signaled.
+
+
+ERRORS
+------
+*EFAULT*::
+At least one of the members of the 'items' array refers to a 'socket' belonging
+to a different application thread.
+*ETERM*::
+At least one of the members of the 'items' array refers to a 'socket' whose
+associated 0MQ 'context' was terminated.
+
+
+EXAMPLE
+-------
+.Polling indefinitely for input events on both a 0MQ socket and a standard socket.
+----
+zmq_pollitem_t items [2];
+/* First item refers to 0MQ socket 'socket' */
+items[0].socket = socket;
+items[0].events = ZMQ_POLLIN;
+/* Second item refers to standard socket 'fd' */
+items[1].socket = NULL;
+items[1].fd = fd;
+items[1].events = ZMQ_POLLIN;
+/* Poll for events indefinitely */
+int rc = zmq_poll (items, 2, -1);
+assert (rc >= 0);
+/* Returned events will be stored in items[].revents */

+zmq_recv \- receive a message from a socket
+.SH "SYNOPSIS"
+.sp
+\fBint zmq_recv (void \fR\fB\fI*socket\fR\fR\fB, zmq_msg_t \fR\fB\fI*msg\fR\fR\fB, int \fR\fB\fIflags\fR\fR\fB);\fR
+.SH "DESCRIPTION"
+.sp
+The \fIzmq_recv()\fR function shall receive a message from the socket referenced by the \fIsocket\fR argument and store it in the message referenced by the \fImsg\fR argument\&. Any content previously stored in \fImsg\fR shall be properly deallocated\&. If there are no messages available on the specified \fIsocket\fR the \fIzmq_recv()\fR function shall block until the request can be satisfied\&. The \fIflags\fR argument is a combination of the flags defined below:
+.PP
+\fBZMQ_NOBLOCK\fR
+.RS 4
+Specifies that the operation should be performed in non\-blocking mode\&. If there are no messages available on the specified
+\fIsocket\fR, the
+\fIzmq_recv()\fR
+function shall fail with
+\fIerrno\fR
+set to EAGAIN\&.
+.RE
+.SS "Multi\-part messages"
+.sp
+A 0MQ message is composed of 1 or more message parts; each message part is an independent \fIzmq_msg_t\fR in its own right\&. 0MQ ensures atomic delivery of messages; peers shall receive either all \fImessage parts\fR of a message or none at all\&.
+.sp
+The total number of message parts is unlimited\&.
+.sp
+An application wishing to determine if a message is composed of multiple parts does so by retrieving the value of the \fIZMQ_RCVMORE\fR socket option on the \fIsocket\fR it is receiving the message from\&. If there are no message parts to follow, or if the message is not composed of multiple parts, \fIZMQ_RCVMORE\fR shall report a value of zero\&. Otherwise, \fIZMQ_RCVMORE\fR shall report a value of 1, indicating that more message parts are to follow\&.
+.SH "RETURN VALUE"
+.sp
+The \fIzmq_recv()\fR function shall return zero if successful\&. Otherwise it shall return \-1 and set \fIerrno\fR to one of the values defined below\&.
+.SH "ERRORS"
+.PP
+\fBEAGAIN\fR
+.RS 4
+Non\-blocking mode was requested and no messages are available at the moment\&.
+.RE
+.PP
+\fBENOTSUP\fR
+.RS 4
+The
+\fIzmq_recv()\fR
+operation is not supported by this socket type\&.
+.RE
+.PP
+\fBEFSM\fR
+.RS 4
+The
+\fIzmq_recv()\fR
+operation cannot be performed on this socket at the moment due to the socket not being in the appropriate state\&. This error may occur with socket types that switch between several states, such as ZMQ_REP\&. See the
+\fImessaging patterns\fR
+section of
+\fBzmq_socket\fR(3)
+for more information\&.
+.RE
+.PP
+\fBETERM\fR
+.RS 4
+The 0MQ
+\fIcontext\fR
+associated with the specified
+\fIsocket\fR
+was terminated\&.

+===========
+
+
+NAME
+----
+zmq_recv - receive a message from a socket
+
+
+SYNOPSIS
+--------
+*int zmq_recv (void '*socket', zmq_msg_t '*msg', int 'flags');*
+
+
+DESCRIPTION
+-----------
+The _zmq_recv()_ function shall receive a message from the socket referenced by
+the 'socket' argument and store it in the message referenced by the 'msg'
+argument. Any content previously stored in 'msg' shall be properly deallocated.
+If there are no messages available on the specified 'socket' the _zmq_recv()_
+function shall block until the request can be satisfied. The 'flags' argument
+is a combination of the flags defined below:
+
+*ZMQ_NOBLOCK*::
+Specifies that the operation should be performed in non-blocking mode. If there
+are no messages available on the specified 'socket', the _zmq_recv()_ function
+shall fail with 'errno' set to EAGAIN.
+
+
+Multi-part messages
+~~~~~~~~~~~~~~~~~~~
+A 0MQ message is composed of 1 or more message parts; each message part is an
+independent 'zmq_msg_t' in its own right. 0MQ ensures atomic delivery of
+messages; peers shall receive either all _message parts_ of a message or none
+at all.
+
+The total number of message parts is unlimited.
+
+An application wishing to determine if a message is composed of multiple parts
+does so by retrieving the value of the _ZMQ_RCVMORE_ socket option on the
+'socket' it is receiving the message from. If there are no message parts to
+follow, or if the message is not composed of multiple parts, _ZMQ_RCVMORE_
+shall report a value of zero. Otherwise, _ZMQ_RCVMORE_ shall report a value of
+1, indicating that more message parts are to follow.
+
+
+RETURN VALUE
+------------
+The _zmq_recv()_ function shall return zero if successful. Otherwise it shall
+return `-1` and set 'errno' to one of the values defined below.
+
+
+ERRORS
+------
+*EAGAIN*::
+Non-blocking mode was requested and no messages are available at the moment.
+*ENOTSUP*::
+The _zmq_recv()_ operation is not supported by this socket type.
+*EFSM*::
+The _zmq_recv()_ operation cannot be performed on this socket at the moment due
+to the socket not being in the appropriate state.  This error may occur with
+socket types that switch between several states, such as ZMQ_REP.  See the
+_messaging patterns_ section of linkzmq:zmq_socket[3] for more information.
+*ETERM*::
+The 0MQ 'context' associated with the specified 'socket' was terminated.

+.sp
+The \fIzmq_send()\fR function shall queue the message referenced by the \fImsg\fR argument to be sent to the socket referenced by the \fIsocket\fR argument\&. The \fIflags\fR argument is a combination of the flags defined below:

+.br
+.sp
+A successful invocation of \fIzmq_send()\fR does not indicate that the message has been transmitted to the network, only that it has been queued on the \fIsocket\fR and 0MQ has assumed responsibility for the message\&.

+.RE
+.SS "Multi\-part messages"
+.sp
+A 0MQ message is composed of 1 or more message parts; each message part is an independent \fIzmq_msg_t\fR in its own right\&. 0MQ ensures atomic delivery of messages; peers shall receive either all \fImessage parts\fR of a message or none at all\&.
+.sp
+The total number of message parts is unlimited\&.
+.sp
+An application wishing to send a multi\-part message does so by specifying the \fIZMQ_SNDMORE\fR flag to \fIzmq_send()\fR\&. The presence of this flag indicates to 0MQ that the message being sent is a multi\-part message and that more message parts are to follow\&. When the application wishes to send the final message part it does so by calling \fIzmq_send()\fR without the \fIZMQ_SNDMORE\fR flag; this indicates that no more message parts are to follow\&.
+.SH "RETURN VALUE"
+.sp
+The \fIzmq_send()\fR function shall return zero if successful\&. Otherwise it shall return \-1 and set \fIerrno\fR to one of the values defined below\&.

+NAME
+----
+zmq_send - send a message on a socket
+
+
+SYNOPSIS
+--------
+*int zmq_send (void '*socket', zmq_msg_t '*msg', int 'flags');*
+
+
+DESCRIPTION
+-----------
+The _zmq_send()_ function shall queue the message referenced by the 'msg'
+argument to be sent to the socket referenced by the 'socket' argument.  The
+'flags' argument is a combination of the flags defined below:
+
+*ZMQ_NOBLOCK*::
+Specifies that the operation should be performed in non-blocking mode. If the
+message cannot be queued on the 'socket', the _zmq_send()_ function shall fail
+with 'errno' set to EAGAIN.
+
+*ZMQ_SNDMORE*::
+Specifies that the message being sent is a multi-part message, and that further
+message parts are to follow. Refer to the section regarding multi-part messages
+below for a detailed description.
+
+NOTE: A successful invocation of _zmq_send()_ does not indicate that the
+message has been transmitted to the network, only that it has been queued on
+the 'socket' and 0MQ has assumed responsibility for the message.
+
+
+Multi-part messages
+~~~~~~~~~~~~~~~~~~~
+A 0MQ message is composed of 1 or more message parts; each message part is an
+independent 'zmq_msg_t' in its own right. 0MQ ensures atomic delivery of
+messages; peers shall receive either all _message parts_ of a message or none
+at all.
+
+The total number of message parts is unlimited.
+
+An application wishing to send a multi-part message does so by specifying the
+'ZMQ_SNDMORE' flag to _zmq_send()_. The presence of this flag indicates to 0MQ
+that the message being sent is a multi-part message and that more message parts
+are to follow. When the application wishes to send the final message part it
+does so by calling _zmq_send()_ without the 'ZMQ_SNDMORE' flag; this indicates
+that no more message parts are to follow.
+
+
+RETURN VALUE
+------------
+The _zmq_send()_ function shall return zero if successful. Otherwise it shall
+return `-1` and set 'errno' to one of the values defined below.
+
+
+ERRORS
+------
+*EAGAIN*::
+Non-blocking mode was requested and the message cannot be sent at the moment.
+*ENOTSUP*::
+The _zmq_send()_ operation is not supported by this socket type.
+*EFSM*::
+The _zmq_send()_ operation cannot be performed on this socket at the moment due
+to the socket not being in the appropriate state.  This error may occur with
+socket types that switch between several states, such as ZMQ_REP.  See the
+_messaging patterns_ section of linkzmq:zmq_socket[3] for more information.

+.SH "NAME"
+zmq_setsockopt \- set 0MQ socket options
+.SH "SYNOPSIS"
+.sp
+\fBint zmq_setsockopt (void \fR\fB\fI*socket\fR\fR\fB, int \fR\fB\fIoption_name\fR\fR\fB, const void \fR\fB\fI*option_value\fR\fR\fB, size_t \fR\fB\fIoption_len\fR\fR\fB);\fR
+.SH "DESCRIPTION"
+.sp
+The \fIzmq_setsockopt()\fR function shall set the option specified by the \fIoption_name\fR argument to the value pointed to by the \fIoption_value\fR argument for the 0MQ socket pointed to by the \fIsocket\fR argument\&. The \fIoption_len\fR argument is the size of the option value in bytes\&.
+.sp
+The following socket options can be set with the \fIzmq_setsockopt()\fR function:
+.SS "ZMQ_HWM: Set high water mark"
+.sp
+The \fIZMQ_HWM\fR option shall set the high water mark for the specified \fIsocket\fR\&. The high water mark is a hard limit on the maximum number of outstanding messages 0MQ shall queue in memory for any single peer that the specified \fIsocket\fR is communicating with\&.
+.sp
+If this limit has been reached the socket shall enter an exceptional state and depending on the socket type, 0MQ shall take appropriate action such as blocking or dropping sent messages\&. Refer to the individual socket descriptions in \fBzmq_socket\fR(3) for details on the exact action taken for each socket type\&.
+.sp
+The default \fIZMQ_HWM\fR value of zero means "no limit"\&.

+.sp
+The \fIZMQ_SWAP\fR option shall set the disk offload (swap) size for the specified \fIsocket\fR\&. A socket which has \fIZMQ_SWAP\fR set to a non\-zero value may exceed it\(cqs high water mark; in this case outstanding messages shall be offloaded to storage on disk rather than held in memory\&.
+.sp
+The value of \fIZMQ_SWAP\fR defines the maximum size of the swap space in bytes\&.

+.SS "ZMQ_AFFINITY: Set I/O thread affinity"
+.sp
+The \fIZMQ_AFFINITY\fR option shall set the I/O thread affinity for newly created connections on the specified \fIsocket\fR\&.
+.sp
+Affinity determines which threads from the 0MQ I/O thread pool associated with the socket\(cqs \fIcontext\fR shall handle newly created connections\&. A value of zero specifies no affinity, meaning that work shall be distributed fairly among all 0MQ I/O threads in the thread pool\&. For non\-zero values, the lowest bit corresponds to thread 1, second lowest bit to thread 2 and so on\&. For example, a value of 3 specifies that subsequent connections on \fIsocket\fR shall be handled exclusively by I/O threads 1 and 2\&.
+.sp
+See also \fBzmq_init\fR(3) for details on allocating the number of I/O threads for a specific \fIcontext\fR\&.

+.sp
+The \fIZMQ_IDENTITY\fR option shall set the identity of the specified \fIsocket\fR\&. Socket identity determines if existing 0MQ infastructure (\fImessage queues\fR, \fIforwarding devices\fR) shall be identified with a specific application and persist across multiple runs of the application\&.
+.sp
+If the socket has no identity, each run of an application is completely separate from other runs\&. However, with identity set the socket shall re\-use any existing 0MQ infrastructure configured by the previous run(s)\&. Thus the application may receive messages that were sent in the meantime, \fImessage queue\fR limits shall be shared with previous run(s) and so on\&.
+.sp
+Identity should be at least one byte and at most 255 bytes long\&. Identities starting with binary zero are reserved for use by 0MQ infrastructure\&.

+.sp
+An empty \fIoption_value\fR of length zero shall subscribe to all incoming messages\&. A non\-empty \fIoption_value\fR shall subscribe to all messages beginning with the specified prefix\&. Mutiple filters may be attached to a single \fIZMQ_SUB\fR socket, in which case a message shall be accepted if it matches at least one filter\&.

+zmq_setsockopt(3)
+=================
+
+
+NAME
+----
+
+zmq_setsockopt - set 0MQ socket options
+
+
+SYNOPSIS
+--------
+*int zmq_setsockopt (void '*socket', int 'option_name', const void '*option_value', size_t 'option_len');*
+
+
+DESCRIPTION
+-----------
+The _zmq_setsockopt()_ function shall set the option specified by the
+'option_name' argument to the value pointed to by the 'option_value' argument
+for the 0MQ socket pointed to by the 'socket' argument. The 'option_len'
+argument is the size of the option value in bytes.
+
+The following socket options can be set with the _zmq_setsockopt()_ function:
+
+
+ZMQ_HWM: Set high water mark
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The 'ZMQ_HWM' option shall set the high water mark for the specified 'socket'.
+The high water mark is a hard limit on the maximum number of outstanding
+messages 0MQ shall queue in memory for any single peer that the specified
+'socket' is communicating with.
+
+If this limit has been reached the socket shall enter an exceptional state and
+depending on the socket type, 0MQ shall take appropriate action such as
+blocking or dropping sent messages. Refer to the individual socket descriptions
+in linkzmq:zmq_socket[3] for details on the exact action taken for each socket
+type.
+
+The default 'ZMQ_HWM' value of zero means "no limit".
+
+[horizontal]
+Option value type:: int64_t
+Option value unit:: messages
+Default value:: 0
+Applicable socket types:: all
+
+
+ZMQ_SWAP: Set disk offload size
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The 'ZMQ_SWAP' option shall set the disk offload (swap) size for the specified
+'socket'. A socket which has 'ZMQ_SWAP' set to a non-zero value may exceed it's
+high water mark; in this case outstanding messages shall be offloaded to
+storage on disk rather than held in memory.
+
+The value of 'ZMQ_SWAP' defines the maximum size of the swap space in bytes.
+
+[horizontal]
+Option value type:: int64_t
+Option value unit:: bytes
+Default value:: 0
+Applicable socket types:: all
+
+
+ZMQ_AFFINITY: Set I/O thread affinity
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The 'ZMQ_AFFINITY' option shall set the I/O thread affinity for newly created
+connections on the specified 'socket'.
+
+Affinity determines which threads from the 0MQ I/O thread pool associated with
+the socket's _context_ shall handle newly created connections.  A value of zero
+specifies no affinity, meaning that work shall be distributed fairly among all
+0MQ I/O threads in the thread pool. For non-zero values, the lowest bit
+corresponds to thread 1, second lowest bit to thread 2 and so on.  For example,
+a value of 3 specifies that subsequent connections on 'socket' shall be handled
+exclusively by I/O threads 1 and 2.
+
+See also linkzmq:zmq_init[3] for details on allocating the number of I/O
+threads for a specific _context_.
+
+[horizontal]
+Option value type:: int64_t
+Option value unit:: N/A (bitmap)
+Default value:: 0
+Applicable socket types:: N/A
+
+
+ZMQ_IDENTITY: Set socket identity
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The 'ZMQ_IDENTITY' option shall set the identity of the specified 'socket'.
+Socket identity determines if existing 0MQ infastructure (_message queues_,
+_forwarding devices_) shall be identified with a specific application and
+persist across multiple runs of the application.
+
+If the socket has no identity, each run of an application is completely
+separate from other runs. However, with identity set the socket shall re-use
+any existing 0MQ infrastructure configured by the previous run(s). Thus the
+application may receive messages that were sent in the meantime, _message
+queue_ limits shall be shared with previous run(s) and so on.
+
+Identity should be at least one byte and at most 255 bytes long. Identities
+starting with binary zero are reserved for use by 0MQ infrastructure.
+
+[horizontal]
+Option value type:: binary data
+Option value unit:: N/A
+Default value:: NULL
+Applicable socket types:: all
+
+
+ZMQ_SUBSCRIBE: Establish message filter
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The 'ZMQ_SUBSCRIBE' option shall establish a new message filter on a 'ZMQ_SUB'
+socket. Newly created 'ZMQ_SUB' sockets shall filter out all incoming messages,
+therefore you should call this option to establish an initial message filter.
+
+An empty 'option_value' of length zero shall subscribe to all incoming
+messages. A non-empty 'option_value' shall subscribe to all messages beginning
+with the specified prefix. Mutiple filters may be attached to a single
+'ZMQ_SUB' socket, in which case a message shall be accepted if it matches at
+least one filter.
+
+[horizontal]
+Option value type:: binary data
+Option value unit:: N/A
+Default value:: N/A
+Applicable socket types:: ZMQ_SUB
+
+
+ZMQ_UNSUBSCRIBE: Remove message filter
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The 'ZMQ_UNSUBSCRIBE' option shall remove an existing message filter on a
+'ZMQ_SUB' socket. The filter specified must match an existing filter previously
+established with the 'ZMQ_SUBSCRIBE' option. If the socket has several
+instances of the same filter attached the 'ZMQ_UNSUBSCRIBE' option shall remove
+only one instance, leaving the rest in place and functional.
+
+[horizontal]
+Option value type:: binary data
+Option value unit:: N/A
+Default value:: N/A
+Applicable socket types:: ZMQ_SUB
+
+
+ZMQ_RATE: Set multicast data rate
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The 'ZMQ_RATE' option shall set the maximum send or receive data rate for
+multicast transports such as linkzmq:zmq_pgm[7] using the specified 'socket'.
+
+[horizontal]
+Option value type:: uint64_t
+Option value unit:: kilobits per second
+Default value:: 100
+Applicable socket types:: all, when using multicast transports
+
+
+ZMQ_RECOVERY_IVL: Set multicast recovery interval
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The 'ZMQ_RECOVERY_IVL' option shall set the recovery interval for multicast
+transports using the specified 'socket'. The recovery interval determines the
+maximum time in seconds that a receiver can be absent from a multicast group
+before unrecoverable data loss will occur.
+
+CAUTION: Excersize care when setting large recovery intervals as the data
+needed for recovery will be held in memory. For example, a 1 minute recovery
+interval at a data rate of 1Gbps requires a 7GB in-memory buffer.
+
+[horizontal]
+Option value type:: uint64_t
+Option value unit:: seconds
+Default value:: 10
+Applicable socket types:: all, when using multicast transports
+
+
+ZMQ_MCAST_LOOP: Control multicast loopback
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The 'ZMQ_MCAST_LOOP' option shall control whether data sent via multicast
+transports using the specified 'socket' can also be received by the sending
+host via loopback. A value of zero disables the loopback functionality, while
+the default value of 1 enables the loopback functionality. Leaving multicast
+loopback enabled when it is not required can have a negative impact on
+performance. Where possible, disable 'ZMQ_MCAST_LOOP' in production
+environments.
+
+[horizontal]
+Option value type:: uint64_t
+Option value unit:: boolean
+Default value:: 1
+Applicable socket types:: all, when using multicast transports
+
+
+ZMQ_SNDBUF: Set kernel transmit buffer size
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The 'ZMQ_SNDBUF' option shall set the underlying kernel transmit buffer size
+for the 'socket' to the specified size in bytes.  A value of zero means leave
+the OS default unchanged. For details please refer to your operating system
+documentation for the 'SO_SNDBUF' socket option.
+
+[horizontal]
+Option value type:: uint64_t
+Option value unit:: bytes
+Default value:: 0
+Applicable socket types:: all
+
+
+ZMQ_RCVBUF: Set kernel receive buffer size
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The 'ZMQ_RCVBUF' option shall set the underlying kernel receive buffer size for
+the 'socket' to the specified size in bytes.  A value of zero means leave the
+OS default unchanged. For details refer to your operating system documentation
+for the 'SO_RCVBUF' socket option.
+
+[horizontal]
+Option value type:: uint64_t
+Option value unit:: bytes
+Default value:: 0
+Applicable socket types:: all
+
+
+RETURN VALUE
+------------
+The _zmq_setsockopt()_ function shall return zero if successful. Otherwise it
+shall return `-1` and set 'errno' to one of the values defined below.
+
+
+ERRORS
+------
+*EINVAL*::
+The requested option _option_name_ is unknown, or the requested _option_len_ or
+_option_value_ is invalid.
+*ETERM*::
+The 0MQ 'context' associated with the specified 'socket' was terminated.

+.SH "NAME"
+zmq_socket \- create 0MQ socket
+.SH "SYNOPSIS"
+.sp
+\fBvoid *zmq_socket (void \fR\fB\fI*context\fR\fR\fB, int \fR\fB\fItype\fR\fR\fB);\fR
+.SH "DESCRIPTION"
+.sp
+The \fIzmq_socket()\fR function shall create a 0MQ socket within the specified \fIcontext\fR and return an opaque handle to the newly created socket\&. The \fItype\fR argument specifies the socket type, which determines the semantics of communication over the socket\&.
+.sp
+The newly created socket is initially unbound, and not associated with any endpoints\&. In order to establish a message flow a socket must first be connected to at least one endpoint with \fBzmq_connect\fR(3), or at least one endpoint must be created for accepting incoming connections with \fBzmq_bind\fR(3)\&.
+.PP
+\fBKey differences to conventional sockets\fR. Generally speaking, conventional sockets present a
+\fIsynchronous\fR
+interface to either connection\-oriented reliable byte streams (SOCK_STREAM), or connection\-less unreliable datagrams (SOCK_DGRAM)\&. In comparison, 0MQ sockets present an abstraction of an asynchronous
+\fImessage queue\fR, with the exact queueing semantics depending on the socket type in use\&. Where conventional sockets transfer streams of bytes or discrete datagrams, 0MQ sockets transfer discrete
+\fImessages\fR\&.
+.sp
+0MQ sockets being \fIasynchronous\fR means that the timings of the physical connection setup and teardown, reconnect and effective delivery are transparent to the user and organized by 0MQ itself\&. Further, messages may be \fIqueued\fR in the event that a peer is unavailable to receive them\&.
+.sp
+Conventional sockets allow only strict one\-to\-one (two peers), many\-to\-one (many clients, one server), or in some cases one\-to\-many (multicast) relationships\&. With the exception of \fIZMQ_PAIR\fR, 0MQ sockets may be connected \fBto multiple endpoints\fR using \fIzmq_connect()\fR, while simultaneously accepting incoming connections \fBfrom multiple endpoints\fR bound to the socket using \fIzmq_bind()\fR, thus allowing many\-to\-many relationships\&.
+.PP
+\fBSocket types\fR. The following sections present the socket types defined by 0MQ, grouped by the general
+\fImessaging pattern\fR
+which is built from related socket types\&.
+.SS "Request\-reply pattern"
+.sp
+The request\-reply pattern is used for sending requests from a \fIclient\fR to one or more instances of a \fIservice\fR, and receiving subsequent replies to each request sent\&.
+.sp

+.nr an-no-space-flag 1
+.nr an-break-flag 1
+.br
+.ps +1
+\fBZMQ_REQ\fR
+.RS 4
+.sp
+A socket of type \fIZMQ_REQ\fR is used by a \fIclient\fR to send requests to and receive replies from a \fIservice\fR\&. This socket type allows only an alternating sequence of \fIzmq_send(request)\fR and subsequent \fIzmq_recv(reply)\fR calls\&. Each request sent is load\-balanced among all \fIservices\fR, and each reply received is matched with the last issued request\&.
+.sp
+When a \fIZMQ_REQ\fR socket enters an exceptional state due to having reached the high water mark for all \fIservices\fR, or if there are no \fIservices\fR at all, then any \fBzmq_send\fR(3) operations on the socket shall block until the exceptional state ends or at least one \fIservice\fR becomes available for sending; messages are not discarded\&.

+<h2 id="_description">DESCRIPTION</h2>

+<div class="sectionbody">

+<div class="paragraph"><p>The <em>zmq_socket()</em> function shall create a ØMQ socket within the specified

+<em>context</em> and return an opaque handle to the newly created socket. The <em>type</em>

+argument specifies the socket type, which determines the semantics of

+communication over the socket.</p></div>

+<div class="paragraph"><p>The newly created socket is initially unbound, and not associated with any

+endpoints. In order to establish a message flow a socket must first be

+connected to at least one endpoint with <a href="zmq_connect.html">zmq_connect(3)</a>, or at least one

+endpoint must be created for accepting incoming connections with

+<a href="zmq_bind.html">zmq_bind(3)</a>.</p></div>

+<div class="paragraph"><div class="title">Key differences to conventional sockets</div><p>Generally speaking, conventional sockets present a <em>synchronous</em> interface to

+either connection-oriented reliable byte streams (SOCK_STREAM), or

+connection-less unreliable datagrams (SOCK_DGRAM). In comparison, ØMQ sockets

+present an abstraction of an asynchronous <em>message queue</em>, with the exact

+queueing semantics depending on the socket type in use. Where conventional

+sockets transfer streams of bytes or discrete datagrams, ØMQ sockets transfer

+discrete <em>messages</em>.</p></div>

+<div class="paragraph"><p>ØMQ sockets being <em>asynchronous</em> means that the timings of the physical

+connection setup and teardown, reconnect and effective delivery are transparent

+to the user and organized by ØMQ itself. Further, messages may be <em>queued</em> in

+the event that a peer is unavailable to receive them.</p></div>

+<div class="paragraph"><p>Conventional sockets allow only strict one-to-one (two peers), many-to-one

+(many clients, one server), or in some cases one-to-many (multicast)

+relationships. With the exception of <em>ZMQ_PAIR</em>, ØMQ sockets may be connected

+<strong>to multiple endpoints</strong> using <em>zmq_connect()</em>, while simultaneously accepting

+incoming connections <strong>from multiple endpoints</strong> bound to the socket using

+<em>zmq_bind()</em>, thus allowing many-to-many relationships.</p></div>

+<div class="paragraph"><div class="title">Socket types</div><p>The following sections present the socket types defined by ØMQ, grouped by the

+general <em>messaging pattern</em> which is built from related socket types.</p></div>

+<h3 id="_request_reply_pattern">Request-reply pattern</h3><div style="clear:left"></div>

+<div class="paragraph"><p>The request-reply pattern is used for sending requests from a <em>client</em> to one

+or more instances of a <em>service</em>, and receiving subsequent replies to each

+request sent.</p></div>

+<h4 id="_zmq_req">ZMQ_REQ</h4>

+<div class="paragraph"><p>A socket of type <em>ZMQ_REQ</em> is used by a <em>client</em> to send requests to and

+receive replies from a <em>service</em>. This socket type allows only an alternating

+sequence of <em>zmq_send(request)</em> and subsequent <em>zmq_recv(reply)</em> calls. Each

+request sent is load-balanced among all <em>services</em>, and each reply received is

+matched with the last issued request.</p></div>

+<div class="paragraph"><p>When a <em>ZMQ_REQ</em> socket enters an exceptional state due to having reached the

+high water mark for all <em>services</em>, or if there are no <em>services</em> at all, then

+any <a href="zmq_send.html">zmq_send(3)</a> operations on the socket shall block until the

+NAME
+----
+zmq_socket - create 0MQ socket
+
+
+SYNOPSIS
+--------
+*void *zmq_socket (void '*context', int 'type');*
+
+
+DESCRIPTION
+-----------
+The 'zmq_socket()' function shall create a 0MQ socket within the specified
+'context' and return an opaque handle to the newly created socket. The 'type'
+argument specifies the socket type, which determines the semantics of
+communication over the socket.
+
+The newly created socket is initially unbound, and not associated with any
+endpoints. In order to establish a message flow a socket must first be
+connected to at least one endpoint with linkzmq:zmq_connect[3], or at least one
+endpoint must be created for accepting incoming connections with
+linkzmq:zmq_bind[3].
+
+.Key differences to conventional sockets
+Generally speaking, conventional sockets present a _synchronous_ interface to
+either connection-oriented reliable byte streams (SOCK_STREAM), or
+connection-less unreliable datagrams (SOCK_DGRAM). In comparison, 0MQ sockets
+present an abstraction of an asynchronous _message queue_, with the exact
+queueing semantics depending on the socket type in use. Where conventional
+sockets transfer streams of bytes or discrete datagrams, 0MQ sockets transfer
+discrete _messages_.
+
+0MQ sockets being _asynchronous_ means that the timings of the physical
+connection setup and teardown, reconnect and effective delivery are transparent
+to the user and organized by 0MQ itself. Further, messages may be _queued_ in
+the event that a peer is unavailable to receive them.
+
+Conventional sockets allow only strict one-to-one (two peers), many-to-one
+(many clients, one server), or in some cases one-to-many (multicast)
+relationships. With the exception of 'ZMQ_PAIR', 0MQ sockets may be connected
+*to multiple endpoints* using _zmq_connect()_, while simultaneously accepting
+incoming connections *from multiple endpoints* bound to the socket using
+_zmq_bind()_, thus allowing many-to-many relationships.
+
+.Socket types
+The following sections present the socket types defined by 0MQ, grouped by the
+general _messaging pattern_ which is built from related socket types.
+
+
+Request-reply pattern
+~~~~~~~~~~~~~~~~~~~~~
+The request-reply pattern is used for sending requests from a _client_ to one
+or more instances of a _service_, and receiving subsequent replies to each
+request sent.
+
+
+ZMQ_REQ
+^^^^^^^
+A socket of type 'ZMQ_REQ' is used by a _client_ to send requests to and
+receive replies from a _service_. This socket type allows only an alternating
+sequence of _zmq_send(request)_ and subsequent _zmq_recv(reply)_ calls. Each
+request sent is load-balanced among all _services_, and each reply received is
+matched with the last issued request.
+
+When a 'ZMQ_REQ' socket enters an exceptional state due to having reached the
+high water mark for all _services_, or if there are no _services_ at all, then
+any linkzmq:zmq_send[3] operations on the socket shall block until the
+exceptional state ends or at least one _service_ becomes available for sending;
+messages are not discarded.
+
+[horizontal]
+.Summary of ZMQ_REQ characteristics
+Compatible peer sockets:: 'ZMQ_REP'
+Direction:: Bidirectional
+Send/receive pattern:: Send, Receive, Send, Receive, ...
+Outgoing routing strategy:: Load-balanced
+Incoming routing strategy:: Last peer
+ZMQ_HWM option action:: Block
+
+
+ZMQ_REP
+^^^^^^^
+A socket of type 'ZMQ_REP' is used by a _service_ to receive requests from and
+send replies to a _client_. This socket type allows only an alternating
+sequence of _zmq_recv(request)_ and subsequent _zmq_send(reply)_ calls. Each
+request received is fair-queued from among all _clients_, and each reply sent
+is routed to the _client_ that issued the last request.
+
+When a 'ZMQ_REP' socket enters an exceptional state due to having reached the
+high water mark for a _client_, then any replies sent to the _client_ in
+question shall be dropped until the exceptional state ends.
+
+[horizontal]
+.Summary of ZMQ_REP characteristics
+Compatible peer sockets:: 'ZMQ_REQ'
+Direction:: Bidirectional
+Send/receive pattern:: Receive, Send, Receive, Send, ...
+Incoming routing strategy:: Fair-queued
+Outgoing routing stratagy:: Last peer
+ZMQ_HWM option action:: Drop
+
+
+Publish-subscribe pattern
+~~~~~~~~~~~~~~~~~~~~~~~~~
+The publish-subscribe pattern is used for one-to-many distribution of data from
+a single _publisher_ to multiple _subscribers_ in a fanout fashion.
+
+
+ZMQ_PUB
+^^^^^^^
+A socket of type 'ZMQ_PUB' is used by a _publisher_ to distribute data.
+Messages sent are distributed in a fanout fashion to all connected peers.
+The linkzmq:zmq_recv[3] function is not implemented for this socket type.
+
+When a 'ZMQ_PUB' socket enters an exceptional state due to having reached the
+high water mark for a _subscriber_, then any messages that would be sent to the
+_subscriber_ in question shall instead be dropped until the exceptional state
+ends.
+
+[horizontal]
+.Summary of ZMQ_PUB characteristics
+Compatible peer sockets:: 'ZMQ_SUB'
+Direction:: Unidirectional
+Send/receive pattern:: Send only
+Incoming routing strategy:: N/A
+Outgoing routing strategy:: Fanout
+ZMQ_HWM option action:: Drop
+
+
+ZMQ_SUB
+^^^^^^^
+A socket of type 'ZMQ_SUB' is used by a _subscriber_ to subscribe to data
+distributed by a _publisher_. Initially a 'ZMQ_SUB' socket is not subscribed to
+any messages, use the 'ZMQ_SUBSCRIBE' option of linkzmq:zmq_setsockopt[3] to
+specify which messages to subscribe to. The _zmq_send()_ function is not
+implemented for this socket type.
+
+[horizontal]
+.Summary of ZMQ_SUB characteristics
+Compatible peer sockets:: 'ZMQ_PUB'
+Direction:: Unidirectional
+Send/receive pattern:: Receive only
+Incoming routing strategy:: Fair-queued
+Outgoing routing strategy:: N/A
+ZMQ_HWM option action:: N/A
+
+
+Pipeline pattern
+~~~~~~~~~~~~~~~~
+The pipeline pattern is used for distributing data to _nodes_ arranged in
+a pipeline. Data always flows down the pipeline, and each stage of the pipeline
+is connected to at least one _node_. When a pipeline stage is connected to
+multiple _nodes_ data is load-balanced among all connected _nodes_.
+
+
+ZMQ_DOWNSTREAM
+^^^^^^^^^^^^^^
+A socket of type 'ZMQ_DOWNSTREAM' is used by a pipeline _node_ to send messages
+to downstream pipeline _nodes_. Messages are load-balanced to all connected
+downstream _nodes_. The _zmq_recv()_ function is not implemented for this
+socket type.
+
+When a 'ZMQ_DOWNSTREAM' socket enters an exceptional state due to having
+reached the high water mark for all downstream _nodes_, or if there are no
+downstream _nodes_ at all, then any linkzmq:zmq_send[3] operations on the
+socket shall block until the exceptional state ends or at least one downstream
+_node_ becomes available for sending; messages are not discarded.
+
+[horizontal]
+.Summary of ZMQ_DOWNSTREAM characteristics
+Compatible peer sockets:: 'ZMQ_UPSTREAM'
+Direction:: Unidirectional
+Send/receive pattern:: Send only
+Incoming routing strategy:: N/A
+Outgoing routing strategy:: Load-balanced
+ZMQ_HWM option action:: Block
+
+
+ZMQ_UPSTREAM
+^^^^^^^^^^^^
+A socket of type 'ZMQ_UPSTREAM' is used by a pipeline _node_ to receive
+messages from upstream pipeline _nodes_. Messages are fair-queued from among
+all connected upstream _nodes_. The _zmq_send()_ function is not implemented
+for this socket type.
+
+[horizontal]
+.Summary of ZMQ_UPSTREAM characteristics
+Compatible peer sockets:: 'ZMQ_DOWNSTREAM'
+Direction:: Unidirectional
+Send/receive pattern:: Receive only
+Incoming routing strategy:: Fair-queued
+Outgoing routing strategy:: N/A
+ZMQ_HWM option action:: N/A
+
+
+Exclusive pair pattern
+~~~~~~~~~~~~~~~~~~~~~~
+The exclusive pair is an advanced pattern used for communicating exclusively
+between two peers.
+
+
+ZMQ_PAIR
+^^^^^^^^
+A socket of type 'ZMQ_PAIR' can only be connected to a single peer at any one
+time.  No message routing or filtering is performed on messages sent over a
+'ZMQ_PAIR' socket.
+
+When a 'ZMQ_PAIR' socket enters an exceptional state due to having reached the
+high water mark for the connected peer, or if no peer is connected, then
+any linkzmq:zmq_send[3] operations on the socket shall block until the peer
+becomes available for sending; messages are not discarded.
+
+NOTE: 'ZMQ_PAIR' sockets are experimental, and are currently missing several
+features such as auto-reconnection.
+
+[horizontal]
+.Summary of ZMQ_PAIR characteristics
+Compatible peer sockets:: 'ZMQ_PAIR'
+Direction:: Bidirectional
+Send/receive pattern:: Unrestricted
+Incoming routing strategy:: N/A
+Outgoing routing strategy:: N/A
+ZMQ_HWM option action:: Block
+
+
+RETURN VALUE
+------------
+The _zmq_socket()_ function shall return an opaque handle to the newly created
+socket if successful. Otherwise, it shall return NULL and set 'errno' to one of
+the values defined below.
+
+
+ERRORS
+------
+*EINVAL*::
+The requested socket 'type' is invalid.
+
+*EMTHREAD*::
+The maximum number of sockets within this 'context' has been exceeded.

+zmq_strerror \- get 0MQ error message string
+.SH "SYNOPSIS"
+.sp
+\fBconst char *zmq_strerror (int \fR\fB\fIerrnum\fR\fR\fB);\fR
+.SH "DESCRIPTION"
+.sp
+The \fIzmq_strerror()\fR function shall return a pointer to an error message string corresponding to the error number specified by the \fIerrnum\fR argument\&. As 0MQ defines additional error numbers over and above those defined by the operating system, applications should use \fIzmq_strerror()\fR in preference to the standard \fIstrerror()\fR function\&.
+.SH "RETURN VALUE"
+.sp
+The \fIzmq_strerror()\fR function shall return a pointer to an error message string\&.
+.SH "ERRORS"
+.sp
+No errors are defined\&.
+.SH "EXAMPLE"
+.PP
+\fBDisplaying an error message when a 0MQ context cannot be initialised\fR. 
+.sp
+.if n \{\

+.SH "NAME"
+zmq_tcp \- 0MQ unicast transport using TCP
+.SH "SYNOPSIS"
+.sp
+TCP is an ubiquitous, reliable, unicast transport\&. When connecting distributed applications over a network with 0MQ, using the TCP transport will likely be your first choice\&.
+.SH "ADDRESSING"
+.sp
+A 0MQ address string consists of two parts as follows: \fItransport\fR://\fIendpoint\fR\&. The \fItransport\fR part specifies the underlying transport protocol to use, and for the TCP transport shall be set to tcp\&. The meaning of the \fIendpoint\fR part for the TCP transport is defined below\&.
+.SS "Assigning a local address to a socket"
+.sp
+When assigning a local address to a socket using \fIzmq_bind()\fR with the \fItcp\fR transport, the \fIendpoint\fR shall be interpreted as an \fIinterface\fR followed by a colon and the TCP port number to use\&.
+.sp
+An \fIinterface\fR may be specified by either of the following:
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+The interface name as defined by the operating system\&.
+.RE
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+The primary IPv4 address assigned to the interface, in it\(cqs numeric representation\&.
+.RE
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+The wildcard
+*, meaning that the interface address is unspecified\&.
+.RE
+.if n \{\
+.sp
+.\}
+.RS 4
+.it 1 an-trap
+.nr an-no-space-flag 1
+.nr an-break-flag 1
+.br
+.ps +1
+\fBNote\fR
+.ps -1
+.br
+.sp
+Interface names are not standardised in any way and should be assumed to be arbitrary and platform dependent\&. On Win32 platforms no short interface names exist, thus only the primary IPv4 address may be used to specify an \fIinterface\fR\&.
+.sp .5v
+.RE
+.SS "Connecting a socket"
+.sp
+When connecting a socket to a peer address using \fIzmq_connect()\fR with the \fItcp\fR transport, the \fIendpoint\fR shall be interpreted as a \fIpeer address\fR followed by a colon and the TCP port number to use\&.
+.sp
+A \fIpeer address\fR may be specified by either of the following:
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+The DNS name of the peer\&.
+.RE
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+The IPv4 address of the peer, in it\(cqs numeric representation\&.
+.RE
+.SH "WIRE FORMAT"
+.sp
+0MQ messages are transmitted over TCP in frames consisting of an encoded \fIpayload length\fR, followed by a \fIflags\fR field and the message body\&. The \fIpayload length\fR is defined as the combined length in octets of the message body and the \fIflags\fR field\&.
+.sp
+For frames with a \fIpayload length\fR not exceeding 254 octets, the \fIpayload length\fR shall be encoded as a single octet\&. The minimum valid \fIpayload length\fR of a frame is 1 octet, thus a \fIpayload length\fR of 0 octets is invalid and such frames SHOULD be ignored\&.
+.sp
+For frames with a \fIpayload length\fR exceeding 254 octets, the \fIpayload length\fR shall be encoded as a single octet with the value 255 followed by the \fIpayload length\fR represented as a 64\-bit unsigned integer in network byte order\&.
+.sp
+The \fIflags\fR field consists of a single octet containing various control flags:
+.sp
+Bit 0 (MORE): \fIMore message parts to follow\fR\&. A value of 0 indicates that there are no more message parts to follow; or that the message being sent is not a multi\-part message\&. A value of 1 indicates that the message being sent is a multi\-part message and more message parts are to follow\&.
+.sp
+Bits 1\-7: \fIReserved\fR\&. Bits 1\-7 are reserved for future expansion and MUST be set to zero\&.
+.sp
+The following ABNF grammar represents a single \fIframe\fR:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+    frame           = (length flags data)
+    length          = OCTET / (escape 8OCTET)
+    flags           = OCTET
+    escape          = %xFF
+    data            = *OCTET

+NAME
+----
+zmq_tcp - 0MQ unicast transport using TCP
+
+
+SYNOPSIS
+--------
+TCP is an ubiquitous, reliable, unicast transport. When connecting distributed
+applications over a network with 0MQ, using the TCP transport will likely be
+your first choice.
+
+
+ADDRESSING
+----------
+A 0MQ address string consists of two parts as follows:
+'transport'`://`'endpoint'. The 'transport' part specifies the underlying
+transport protocol to use, and for the TCP transport shall be set to `tcp`.
+The meaning of the 'endpoint' part for the TCP transport is defined below.
+
+
+Assigning a local address to a socket
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+When assigning a local address to a socket using _zmq_bind()_ with the 'tcp'
+transport, the 'endpoint' shall be interpreted as an 'interface' followed by a
+colon and the TCP port number to use.
+
+An 'interface' may be specified by either of the following:
+
+* The interface name as defined by the operating system.
+* The primary IPv4 address assigned to the interface, in it's numeric representation.
+* The wildcard `*`, meaning that the interface address is unspecified.
+
+NOTE: Interface names are not standardised in any way and should be assumed to
+be arbitrary and platform dependent. On Win32 platforms no short interface
+names exist, thus only the primary IPv4 address may be used to specify an
+'interface'.
+
+Connecting a socket
+~~~~~~~~~~~~~~~~~~~
+When connecting a socket to a peer address using _zmq_connect()_ with the 'tcp'
+transport, the 'endpoint' shall be interpreted as a 'peer address' followed by
+a colon and the TCP port number to use.
+
+A 'peer address' may be specified by either of the following:
+
+* The DNS name of the peer.
+* The IPv4 address of the peer, in it's numeric representation.
+
+
+WIRE FORMAT
+-----------
+0MQ messages are transmitted over TCP in frames consisting of an encoded
+'payload length', followed by a 'flags' field and the message body. The 'payload
+length' is defined as the combined length in octets of the message body and the
+'flags' field.
+
+For frames with a 'payload length' not exceeding 254 octets, the 'payload
+length' shall be encoded as a single octet.  The minimum valid 'payload length'
+of a frame is 1 octet, thus a 'payload length' of 0 octets is invalid and such
+frames SHOULD be ignored.
+
+For frames with a 'payload length' exceeding 254 octets, the 'payload length'
+shall be encoded as a single octet with the value `255` followed by the
+'payload length' represented as a 64-bit unsigned integer in network byte
+order.
+
+The 'flags' field consists of a single octet containing various control flags:
+
+Bit 0 (MORE): _More message parts to follow_. A value of 0 indicates that there
+are no more message parts to follow; or that the message being sent is not a
+multi-part message. A value of 1 indicates that the message being sent is a
+multi-part message and more message parts are to follow.
+
+Bits 1-7: _Reserved_. Bits 1-7 are reserved for future expansion and MUST be
+set to zero.
+
+The following ABNF grammar represents a single 'frame':
+
+....
+    frame           = (length flags data)
+    length          = OCTET / (escape 8OCTET)
+    flags           = OCTET
+    escape          = %xFF
+    data            = *OCTET
+....
+
+The following diagram illustrates the layout of a frame with a 'payload length'
+not exceeding 254 octets:
+
+....
+0                   1                   2                   3

+\fBint zmq_term (void \fR\fB\fI*context\fR\fR\fB);\fR
+.SH "DESCRIPTION"
+.sp
+The \fIzmq_term()\fR function terminates the 0MQ context \fIcontext\fR\&.
+.sp
+If there are no longer any sockets open within \fIcontext\fR at the time \fIzmq_term()\fR is called then \fIcontext\fR shall be shut down and all associated resources shall be released immediately\&.
+.sp
+Otherwise, the following applies:
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+The
+\fIzmq_term()\fR
+function shall return immediately\&.

+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+Any blocking operations currently in progress on sockets open within
+\fIcontext\fR
+shall return immediately with an error code of ETERM\&.
+.RE
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+With the exception of
+\fIzmq_close()\fR, any further operations on sockets open within
+\fIcontext\fR
+shall fail with an error code of ETERM\&.
+.RE
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3

+The actual shutdown of
+\fIcontext\fR, and release of any associated resources,
+\fBshall be delayed\fR
+until the last socket within it is closed with
+\fIzmq_close()\fR\&.
+.RE
+.SH "RETURN VALUE"
+.sp
+The \fIzmq_term()\fR function shall return zero if successful\&. Otherwise it shall return \-1 and set \fIerrno\fR to one of the values defined below\&.

+
+* Any blocking operations currently in progress on sockets open within
+  'context' shall return immediately with an error code of ETERM.
+
+* With the exception of _zmq_close()_, any further operations on sockets open
+  within 'context' shall fail with an error code of ETERM.
+
+* The actual shutdown of 'context', and release of any associated resources,
+  *shall be delayed* until the last socket within it is closed with
+  _zmq_close()_.
+
+
+RETURN VALUE
+------------
+The _zmq_term()_ function shall return zero if successful. Otherwise it shall
+return `-1` and set 'errno' to one of the values defined below.

+zmq_version - report 0MQ library version
+
+
+SYNOPSIS
+--------
+*void zmq_version (int '*major', int '*minor', int '*patch');*
+
+
+DESCRIPTION
+-----------
+The _zmq_version()_ function shall fill in the integer variables pointed to by
+the 'major', 'minor' and 'patch' arguments with the major, minor and patchlevel
+components of the 0MQ library version.
+
+This functionality is intended for applications or language bindings
+dynamically linking to the 0MQ library that wish to determine the actual
+version of the 0MQ library they are using.
+
+
+RETURN VALUE
+------------
+There is no return value.
+
+
+ERRORS
+------
+No errors are defined.
+
+
+EXAMPLE
+-------
+.Printing out the version of the 0MQ library
+----
+int major, minor, patch;
+zmq_version (&major, &minor, &patch);
+printf ("Current 0MQ version is %d.%d.%d\n", major, minor, patch);

+/**
+ ****************************************************************************
+ * <P> XML.c - implementation file for basic XML parser written in ANSI C++
+ * for portability. It works by using recursion and a node tree for breaking
+ * down the elements of an XML document.  </P>
+ *
+ * @version     V2.39
+ * @author      Frank Vanden Berghen
+ *
+ * NOTE:
+ *
+ *   If you add "#define STRICT_PARSING", on the first line of this file
+ *   the parser will see the following XML-stream:
+ *      <a><b>some text</b><b>other text    </a>
+ *   as an error. Otherwise, this tring will be equivalent to:
+ *      <a><b>some text</b><b>other text</b></a>
+ *
+ * NOTE:
+ *
+ *   If you add "#define APPROXIMATE_PARSING" on the first line of this file
+ *   the parser will see the following XML-stream:
+ *     <data name="n1">
+ *     <data name="n2">
+ *     <data name="n3" />
+ *   as equivalent to the following XML-stream:
+ *     <data name="n1" />
+ *     <data name="n2" />
+ *     <data name="n3" />
+ *   This can be useful for badly-formed XML-streams but prevent the use
+ *   of the following XML-stream (problem is: tags at contiguous levels
+ *   have the same names):
+ *     <data name="n1">
+ *        <data name="n2">
+ *            <data name="n3" />
+ *        </data>
+ *     </data>
+ *
+ * NOTE:
+ *
+ *   If you add "#define _XMLPARSER_NO_MESSAGEBOX_" on the first line of this file
+ *   the "openFileHelper" function will always display error messages inside the
+ *   console instead of inside a message-box-window. Message-box-windows are
+ *   available on windows 9x/NT/2000/XP/Vista only.

+ * \section tutorial First Tutorial
+ * You can follow a simple <a href="../../xmlParser.html">Tutorial</a> to know the basics...
+ *
+ * \section usage General usage: How to include the XMLParser library inside your project.
+ *
+ * The library is composed of two files: <a href="../../xmlParser.cpp">xmlParser.cpp</a> and
+ * <a href="../../xmlParser.h">xmlParser.h</a>. These are the ONLY 2 files that you need when
+ * using the library inside your own projects.
+ *
+ * All the functions of the library are documented inside the comments of the file
+ * <a href="../../xmlParser.h">xmlParser.h</a>. These comments can be transformed in
+ * full-fledged HTML documentation using the DOXYGEN software: simply type: "doxygen doxy.cfg"
+ *
+ * By default, the XMLParser library uses (char*) for string representation.To use the (wchar_t*)
+ * version of the library, you need to define the "_UNICODE" preprocessor definition variable
+ * (this is usually done inside your project definition file) (This is done automatically for you
+ * when using Visual Studio).
+ *
+ * \section example Advanced Tutorial and Many Examples of usage.
+ *
+ * Some very small introductory examples are described inside the Tutorial file
+ * <a href="../../xmlParser.html">xmlParser.html</a>
+ *
+ * Some additional small examples are also inside the file <a href="../../xmlTest.cpp">xmlTest.cpp</a>
+ * (for the "char*" version of the library) and inside the file
+ * <a href="../../xmlTestUnicode.cpp">xmlTestUnicode.cpp</a> (for the "wchar_t*"
+ * version of the library). If you have a question, please review these additionnal examples
+ * before sending an e-mail to the author.
+ *
+ * To build the examples:
+ * - linux/unix: type "make"
+ * - solaris: type "make -f makefile.solaris"
+ * - windows: Visual Studio: double-click on xmlParser.dsw
+ *   (under Visual Studio .NET, the .dsp and .dsw files will be automatically converted to .vcproj and .sln files)
+ *
+ * In order to build the examples you need some additional files:
+ * - linux/unix: makefile
+ * - solaris: makefile.solaris
+ * - windows: Visual Studio: *.dsp, xmlParser.dsw and also xmlParser.lib and xmlParser.dll

+ * \section debugging Debugging with the XMLParser library
+ *
+ * \subsection debugwin Debugging under WINDOWS
+ *
+ * 	Inside Visual C++, the "debug versions" of the memory allocation functions are
+ * 	very slow: Do not forget to compile in "release mode" to get maximum speed.
+ * 	When I have to debug a software that is using the XMLParser Library, it was usually
+ * 	a nightmare because the library was sooOOOoooo slow in debug mode (because of the
+ *  slow memory allocations in Debug mode). To solve this
+ * 	problem, during all the debugging session, I use a very fast DLL version of the
+ * 	XMLParser Library (the DLL is compiled in release mode). Using the DLL version of
+ * 	the XMLParser Library allows me to have lightening XML parsing speed even in debug!
+ * 	Other than that, the DLL version is useless: In the release version of my tool,
+ * 	I always use the normal, ".cpp"-based, XMLParser Library (I simply include the
+ * <a href="../../xmlParser.cpp">xmlParser.cpp</a> and
+ * <a href="../../xmlParser.h">xmlParser.h</a> files into the project).
+ *
+ * 	The file <a href="../../XMLNodeAutoexp.txt">XMLNodeAutoexp.txt</a> contains some
+ * "tweaks" that improve substancially the display of the content of the XMLNode objects
+ * inside the Visual Studio Debugger. Believe me, once you have seen inside the debugger
+ * the "smooth" display of the XMLNode objects, you cannot live without it anymore!
+ *
+ * \subsection debuglinux Debugging under LINUX/UNIX
+ *
+ * 	The speed of the debug version of the XMLParser library is tolerable so no extra
+ * work.has been done.

+     *     XMLNode::parseFile and XMLNode::openFileHelper functions will test if the file contains ASCII
+     *     characters. If this is the case, then the file will be loaded and converted in memory to
+     *     WideChar before being parsed. If 0, no conversion will be performed.
+     *
+     * @param guessWideCharChars If "guessWideCharChars"=1 and if this library is compiled in ASCII/UTF8/char* mode, then the
+     *     XMLNode::parseFile and XMLNode::openFileHelper functions will test if the file contains WideChar
+     *     characters. If this is the case, then the file will be loaded and converted in memory to
+     *     ASCII/UTF8/char* before being parsed. If 0, no conversion will be performed.
+     *
+     * @param characterEncoding This parameter is only meaningful when compiling in char* mode (multibyte character mode).
+     *     In wchar_t* (wide char mode), this parameter is ignored. This parameter should be one of the
+     *     three currently recognized encodings: XMLNode::encoding_UTF8, XMLNode::encoding_ascii,
+     *     XMLNode::encoding_ShiftJIS.
+     *
+     * @param dropWhiteSpace In most situations, text fields containing only white spaces (and carriage returns)
+     *     are useless. Even more, these "empty" text fields are annoying because they increase the
+     *     complexity of the user's code for parsing. So, 99% of the time, it's better to drop
+     *     the "empty" text fields. However The XML specification indicates that no white spaces
+     *     should be lost when parsing the file. So to be perfectly XML-compliant, you should set
+     *     dropWhiteSpace=0. A note of caution: if you set "dropWhiteSpace=0", the parser will be
+     *     slower and your code will be more complex.
+     *
+     * @param removeCommentsInMiddleOfText To explain this parameter, let's consider this code:
+     * \code
+     *        XMLNode x=XMLNode::parseString("<a>foo<!-- hello -->bar<!DOCTYPE world >chu</a>","a");
+     * \endcode
+     *     If removeCommentsInMiddleOfText=0, then we will have:
+     * \code
+     *        x.getText(0) -> "foo"
+     *        x.getText(1) -> "bar"
+     *        x.getText(2) -> "chu"
+     *        x.getClear(0) --> "<!-- hello -->"
+     *        x.getClear(1) --> "<!DOCTYPE world >"
+     * \endcode
+     *     If removeCommentsInMiddleOfText=1, then we will have:
+     * \code
+     *        x.getText(0) -> "foobar"
+     *        x.getText(1) -> "chu"
+     *        x.getClear(0) --> "<!DOCTYPE world >"
+     * \endcode
+     *
+     * \return "0" when there are no errors. If you try to set an unrecognized encoding then the return value will be "1" to signal an error.
+     *
+     * \note Sometime, it's useful to set "guessWideCharChars=0" to disable any conversion
+     * because the test to detect the file-type (ASCII/UTF8/char* or WideChar) may fail (rarely). */
