zmq_disconnect - Man Page

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

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 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)

The zmq_disconnect() function shall return zero if successful. Otherwise it shall return -1 and set errno to one of the values defined below.

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.

/* 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);
