# xs_term(3) Manual Page

## NAME

xs_term - terminate the context

## SYNOPSIS

int xs_term (void *context);

## DESCRIPTION

The xs_term() function shall terminate the Crossroads 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 xs_close(), any further operations on sockets open within context shall fail with an error code of ETERM.

2. After interrupting all blocking calls, xs_term() shall block until the following conditions are satisfied:

   - All sockets open within context have been closed with xs_close().

   - For each socket within context, all messages sent by the application with xs_send() have either been physically transferred to a network peer, or the socket’s linger period set with the XS_LINGER socket option has expired.

For further details regarding socket linger behaviour refer to the XS_LINGER option in xs_setsockopt(3).

## RETURN VALUE

The xs_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.
