+zmq_disconnect - Disconnect a socket
+
+
+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. 
+
+The 'endpoint' argument is as described in linkzmq:zmq_connect[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.
+
+
+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);
