#include <sys/asyncmsg.h>
int asyncmsg_flush( int coid,
int mode );
- 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.

Use the -l asyncmsg option to
qcc
to link against this library.
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.
EOK, or -1 if an error occurred
(errno is set).
- EBADF
- The connection specified by coid doesn't exist.
