# zmq_ctx_destroy(3) Manual Page

## NAME

zmq_ctx_destroy - terminate a 0MQ context

## SYNOPSIS

int zmq_ctx_destroy (void *context);

## DESCRIPTION

The zmq_ctx_destroy() function shall destroy the ØMQ 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_destroy() 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 behaviour refer to the ZMQ_LINGER option in zmq_setsockopt(3).

This function is deprecated by zmq_ctx_term(3).

## RETURN VALUE

The zmq_ctx_destroy() 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.
