Pause a channel that's capturing
#include <sys/asoundlib.h> int snd_pcm_capture_pause ( snd_pcm_t *pcm );
The snd_pcm_capture_pause() function pauses a channel that's capturing. Unlike draining or flushing, this preserves all data that has not yet been received within the audio driver, to be retrieved after resuming.
EOK on success, a negative errno upon failure. The errno values are available in the errno.h file.
