ZMQ_CLOSE(3)                      0MQ Manual                      ZMQ_CLOSE(3)

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.
