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.
