ZMQ_CTX_DESTROY(3) 0MQ Manual ZMQ_CTX_DESTROY(3)

zmq_ctx_destroy - destroy a 0MQ context

int zmq_ctx_destroy (void *context);

The zmq_ctx_destroy() 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_destroy() 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 behavior refer to the ZMQ_LINGER option in zmq_setsockopt(3).

This function replaces the deprecated function zmq_term(3).

The zmq_ctx_destroy() 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.

zmq(7) zmq_init(3) zmq_close(3) zmq_setsockopt(3)
