zmq_ctx_term(3) =============== NAME ---- zmq_ctx_term - destroy a 0MQ context SYNOPSIS -------- *int zmq_ctx_term (void '*context');* DESCRIPTION ----------- 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 behavior refer to the _ZMQ_LINGER_ option in linkzmq:zmq_setsockopt[3]. This function replaces the deprecated function linkzmq:zmq_term[3]. WARNING ------- As _ZMQ_LINGER_ defaults to "infinite", by default this function will block indefinitely if there are any pending connects or sends. We strongly recommend to (a) set _ZMQ_LINGER_ to zero on all sockets and (b) close all sockets, before calling this function. RETURN VALUE ------------ 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. ERRORS ------ *EFAULT*:: The provided 'context' was invalid. *EINTR*:: Termination was interrupted by a signal. It can be restarted if needed.
