Close a PCM handle and free its resources
#include <sys/asoundlib.h> int snd_pcm_close( snd_pcm_t *handle );
Use the -l asound option to qcc to link against this library.
The snd_pcm_close() function frees all resources allocated with the audio handle and closes the connection to the PCM interface.
Zero on success, or a negative value on error.
- The close() call was interrupted by a signal.
- The state of handle is invalid or an invalid state change occurred. You can call snd_pcm_channel_status() to check if the state change was invalid.
- An I/O error occurred while updating the directory information.
- A previous buffered write call has failed.

This function is not thread safe if handle (snd_pcm_t) is used across multiple threads.
