ZMQ_CTX_TERM(3) 0MQ Manual ZMQ_CTX_TERM(3)NAMEzmq_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).
WARNING
As ZMQ_LINGER defaults to "infinite", by default this function will
block indefinitely if there are any pending connects or sends. We
strongly recommend to (a) set ZMQ_LINGER to zero on all sockets and (b)
close all sockets, before calling this function.
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.
