zmq_ctx_term(3)

NAME

zmq_ctx_term - terminate a 0MQ context

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:

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_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

This function replaces the deprecated functions zmq_term and zmq_ctx_destroy

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.

EFAULT: The provided 'context' was invalid.
EINTR: Termination was interrupted by a signal. It can be restarted if needed.
