int zmq_connect (void *socket, const char *endpoint);
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:
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 zmq_socket(3) for a description of the exact semantics involved when connecting or binding a socket to multiple endpoints.
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.
The zmq_connect() function shall return zero if successful. Otherwise it shall return -1 and set errno to one of the values defined below.
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 */ rc = zmq_connect (socket, "tcp://server001:5555"); assert (rc == 0);
