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 zmq_setsockopt(3).

       This function replaces the deprecated function 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.
