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'.
|
|
|
|
_zmq_close()_ must be called exactly once for each socket. If it is never called,
|
|
_zmq_ctx_term()_ will block forever. If it is called multiple times for the same
|
|
socket or if 'socket' does not point to a socket, the behaviour is undefined.
|
|
|
|
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 linkzmq:zmq_setsockopt[3] and linkzmq:zmq_ctx_term[3].
|
|
|
|
NOTE: This API will complete asynchronously, so not everything will be deallocated
|
|
after it returns. See above for details about linger.
|
|
|
|
|
|
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 NULL.
