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 zmq_setsockopt(3).

This function replaces the deprecated function zmq_term(3).

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.
