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 zmq_inproc(7)

       ipc
           local inter-process communication transport, see zmq_ipc(7)

       tcp
           unicast transport using TCP, see zmq_tcp(7)

       pgm, epgm
           reliable multicast transport using PGM, see 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 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

       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.

       ETERM
           The 0MQ 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

       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);
