Stopping the capture

If your application wishes to stop capturing, it can simply stop reading data and let the subchannel overrun as described above, but there's a better way.

If you want your application to stop capturing immediately and delete any unread data from the hardware buffer, call one the flush functions:

• snd_pcm_plugin_flush() if you're using the plugins
• snd_pcm_channel_flush() or snd_pcm_capture_flush() if you aren't
