NAME

       zmq_close - close 0MQ socket

SYNOPSIS

       int zmq_close (void *socket);

DESCRIPTION

       The zmq_close() function shall destroy the socket referenced by the socket argument. Any
       outstanding messages physically received from the network but not yet received by the
       application with zmq_recv() shall be discarded. The behaviour for discarding messages sent
       by the application with zmq_send() but not yet physically transferred to the network
       depends on the value of the ZMQ_LINGER socket option for the specified socket.

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

RETURN VALUE

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

ERRORS

       ENOTSOCK
           The provided socket was invalid.
