Destroy an asynchronous message channel

Asynchronous messaging is an experimental feature;

experimental software, see the Commercial Software License Agreement (CSLA) or

#include <sys/asyncmsg.h>
int asyncmsg_channel_destroy( int chid );
- chid
- The ID of the channel to destroy.
libasyncmsg
Use the -l asyncmsg option to
qcc
to link against this library.
The asyncmsg_channel_destroy() function destroys the asynchronous message channel
specified by chid.
If you provided a callback function when you called
asyncmsg_channel_create(),
asyncmsg_channel_destroy() invokes the callback to free any
outstanding receive buffers; otherwise, asyncmsg_channel_destroy()
uses
free().
EOK, or -1 if an error occurred
(errno is set).
- EINVAL
- The channel specified by chid doesn't exist.
