zmq_ctx_term(3)
===============
NAME
----
zmq_ctx_term - destroy a 0MQ context
SYNOPSIS
--------
*int zmq_ctx_term (void '*context');*
DESCRIPTION
-----------
The _zmq_ctx_term()_ function shall destroy the 0MQ context 'context'.
Context termination is performed in the following steps:
1. Any blocking operations currently in progress on sockets open within
'context' shall return immediately with an error code of ETERM. With the
exception of _zmq_close()_, any further operations on sockets open within
'context' shall fail with an error code of ETERM.
2. After interrupting all blocking calls, _zmq_ctx_term()_ shall _block_ until
the following conditions are satisfied:
* All sockets open within 'context' have been closed with _zmq_close()_.
* For each socket within 'context', all messages sent by the application
with _zmq_send()_ have either been physically transferred to a network
peer, or the socket's linger period set with the _ZMQ_LINGER_ socket
option has expired.
For further details regarding socket linger behaviour refer to the _ZMQ_LINGER_
option in linkzmq:zmq_setsockopt[3].
This function replaces the deprecated function linkzmq:zmq_term[3].
RETURN VALUE
------------
The _zmq_ctx_term()_ function shall return zero if successful. Otherwise
it shall return `-1` and set 'errno' to one of the values defined below.
ERRORS
------
*EFAULT*::
The provided 'context' was invalid.
*EINTR*::
Termination was interrupted by a signal. It can be restarted if needed.
