ZMQ_DISCONNECT(3) 0MQ Manual ZMQ_DISCONNECT(3) 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 longer be able to queue outgo- ing 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); SEE ALSO zmq_connect(3) zmq_socket(3) zmq(7) AUTHORS This page was written by the 0MQ community.
