zmq_flush(3)
|
|
============
|
|
|
|
|
|
NAME
|
|
----
|
|
zmq_flush - flushes pre-sent messages to the socket
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
'int zmq_flush (void *s);'
|
|
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Flushes all the pre-sent messages - i.e. those that have been sent with
|
|
ZMQ_NOFLUSH flag - to the socket. This functionality improves performance in
|
|
cases where several messages are sent during a single business operation.
|
|
It should not be used as a transaction - ACID properties are not guaranteed.
|
|
Note that calling 'zmq_send' without ZMQ_NOFLUSH flag automatically flushes all
|
|
previously pre-sent messages.
|
|
|
|
|
|
RETURN VALUE
|
|
------------
|
|
In case of success the function returns zero. Otherwise it returns -1 and
|
|
sets 'errno' to the appropriate value.
|
|
|
|
|
|
ERRORS
|
|
------
|
|
*ENOTSUP*::
|
|
function isn't supported by particular socket type.
|
|
*EFSM*::
|
|
function cannot be called at the moment, because socket is not in the
|
|
approprite state.
