int zmq_ctx_term (void *context);
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.
After interrupting all blocking calls,
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 behavior refer to the ZMQ_LINGER option in zmq_setsockopt(3).
This function replaces the deprecated function zmq_term(3).
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.
- The provided context was invalid.
- Termination was interrupted by a signal. It can be restarted if needed.
