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 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 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.
