NAME

       zmq_disconnect - Disconnect a socket from an endpoint

SYNOPSIS

       int zmq_disconnect (void *socket, const char *endpoint);

DESCRIPTION

       The zmq_disconnect() function shall disconnect a socket specified by the socket argument
       from the endpoint specified by the endpoint argument. Note the actual disconnect system
       call might occur at a later time.

       Upon disconnection the will also stop receiving messages originating from this endpoint.
       Moreover, the socket will no longuer be able to queue outgoing messages to this endpoint.
       The outgoing message queue associated with the endpoint will be discarded. However, if the
       socket’s linger period is non-zero, libzmq will still attempt to transmit these discarded
       messages, until the linger period expires.

       The endpoint argument is as described in zmq_connect(3)

           Note
           The default setting of ZMQ_LINGER does not discard unsent messages; this behaviour may
           cause the application to block when calling zmq_ctx_term(). For details refer to
           zmq_setsockopt(3) and zmq_ctx_term(3).

RETURN VALUE

       The zmq_disconnect() 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.

       ETERM
           The 0MQ context associated with the specified socket was terminated.

       ENOTSOCK
           The provided socket was invalid.

       ENOENT
           The provided endpoint is not in use by the socket.

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 the host server001, port 5555 using a TCP transport */
           rc = zmq_connect (socket, "tcp://server001:5555");
           assert (rc == 0);
           /* Disconnect from the previously connected endpoint */
           rc = zmq_disconnect (socket, "tcp://server001:5555");
           assert (rc == 0);
