zmq_connect(3)
==============
NAME
----
zmq_connect - connect a socket to a peer address
SYNOPSIS
--------
*int zmq_connect (void '*socket', const char '*address');*
DESCRIPTION
-----------
The _zmq_connect()_ function shall connect the socket referenced by the
'socket' argument to a peer address specified by the 'address' argument.
The 'address' argument is a string consisting of two parts as follows:
'transport'`://`'endpoint'. The 'transport' part specifies the underlying
transport protocol to use. The meaning of the 'endpoint' part is specific to
the underlying transport protocol selected.
The following transports are defined:
'tcp':: unicast transport using TCP, see linkzmq:zmq_tcp[7]
'pgm', 'epgm':: reliable multicast transport using PGM, see linkzmq:zmq_pgm[7]
'ipc':: local inter-process communication transport, see linkzmq:zmq_ipc[7]
'inproc':: local in-process (inter-thread) communication transport, see linkzmq:zmq_inproc[7]
A single socket may be connected to an arbitrary number of peer addresses using
_zmq_connect()_, while also having an arbitrary number of local addresses
assigned to it using _zmq_bind()_.
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.
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 endpoint '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 */
rc = zmq_connect (socket, "tcp://server001:5555");
assert (rc == 0);
