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 zmq_tcp(7)

       pgm, epgm
           reliable multicast transport using PGM, see zmq_pgm(7)

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

       inproc
           local in-process (inter-thread) communication transport, see
           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

       Example 1. 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);
