NAME

zmq_ctx_term - terminate 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 socketcqs 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 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.
