Flush the asynchronous messages sent through a connection
CAUTION:
Asynchronous messaging is an experimental feature;
for information about the use of
experimental software, see the Commercial Software License Agreement (CSLA) or
Partner Software License Agreement (PSLA) in the Licensing area of our website,
http://www.qnx.com/legal/licensing/.
Note:
Asynchronous messaging support is in its own kernel module.
In order to use it, you must add [module=async] to the procnto
line of your mkifs buildfile.
Synopsis:
#include <sys/asyncmsg.h>
int asyncmsg_flush( int coid,
int mode );
Arguments:
- coid
- The connection ID of the connection you want to flush.
- mode
- 0, or ASYNCMSG_FLUSH_NONBLOCK if you don't want the
function to block.
Library:
libasyncmsg
Use the -l asyncmsg option to
qcc
to link against this library.
Description:
The asyncmsg_flush() function flushes the messages sent through the
connection specified by the connection ID coid argument.
If you don't specify a mode of ASYNCMSG_FLUSH_NONBLOCK,
the function doesn't return until all the existing messages are delivered to
the receive side.
Returns:
EOK, or -1 if an error occurred
(errno is set).
Errors:
- EBADF
- The connection specified by coid doesn't exist.
