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 linkxs:xs_inproc[7] +'ipc':: local inter-process communication transport, see linkxs:xs_ipc[7] +'tcp':: unicast transport using TCP, see linkxs:xs_tcp[7] +'pgm', 'epgm':: reliable multicast transport using PGM, see linkxs:xs_pgm[7] + +With the exception of 'XS_PAIR' sockets, a single socket may be connected to +multiple endpoints using _xs_connect()_, while simultaneously accepting +incoming connections from multiple endpoints bound to the socket using +_xs_bind()_. Refer to linkxs:xs_socket[3] for a description of the exact +semantics involved when connecting or binding a socket to multiple endpoints. + + +RETURN VALUE +------------ +The _xs_bind()_ function shall return zero if successful. Otherwise it shall +return `-1` and set 'errno' to one of the values defined below. + + +ERRORS +------ +*EINVAL*:: +The endpoint supplied is invalid. +*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 'context' associated with the specified 'socket' was terminated. +*ENOTSOCK*:: +The provided 'socket' was invalid. +*EMTHREAD*:: +No I/O thread is available to accomplish the task. + + +EXAMPLE +------- +.Binding a publisher socket to an in-process and a TCP transport +---- +/* Create a XS_PUB socket */ +void *socket = xs_socket (context, XS_PUB); +assert (socket); +/* Bind it to a in-process transport with the address 'my_publisher' */ +int rc = xs_bind (socket, "inproc://my_publisher"); +assert (rc == 0); +/* Bind it to a TCP transport on port 5555 of the 'eth0' interface */ +rc = xs_bind (socket, "tcp://eth0:5555"); +assert (rc == 0); +---- + + +SEE ALSO +-------- +linkxs:xs_connect[3] +linkxs:xs_socket[3] +linkxs:xs[7] + + +AUTHORS +------- +The Crossroads documentation was written by Martin Sustrik +and Martin Lucina . -- cgit v1.2.3
