0MQ 4.3.5                                          03/31/2024                                  ZMQ_DISCONNECT(3)

       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)

           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).

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.
