NAME¶
zmq_ctx_term - terminate a 0MQ contextSYNOPSIS¶
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 zmq_setsockopt(3).
This function replaces the deprecated functions zmq_term(3) and zmq_ctx_destroy(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¶
EFAULTThe provided context was invalid.
EINTR
Termination was interrupted by a signal. It can be
restarted if needed.
