ZMQ_CTX_TERM(3) 0MQ Manual ZMQ_CTX_TERM(3)

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:

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).

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.
