ØMQ Manual - ØMQ/3.1.0
zmq_term - terminate ØMQ context
int zmq_term (void *context);
The zmq_term() function shall terminate the ØMQ context context.
Context termination is performed in the following steps:
- 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.
- After interrupting all blocking calls, zmq_term() shall block until the following conditions are satisfied: <itemizedlist> <listitem> 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).
The zmq_term() function shall return zero if successful. Otherwise it shall return -1 and set errno to one of the values defined below.
- The provided context was invalid.
- Termination was interrupted by a signal. It can be restarted if needed.
