NAMEzmq_ctx_term − terminate a 0MQ context

SYNOPSISint zmq_ctx_term (void *context);

DESCRIPTIONThe 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 sockets 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)​.

RETURN VALUEThe zmq_ctx_term() function shall return zero if successful​. Otherwise it shall return −1 and set errno to one of the values defined below​.

ERRORSEFAULT The provided context was invalid​. EINTR Termination was interrupted by a signal​. It can be restarted if needed​.
