Get the current configuration for the specified PCM channel
#include <sys/asoundlib.h> int snd_pcm_channel_setup( snd_pcm_t *handle, snd_pcm_channel_setup_t *setup );
- The handle for the PCM device, which you must have opened by calling snd_pcm_open_name(), snd_pcm_open(), or snd_pcm_open_preferred().
- A pointer to a
structure that snd_pcm_channel_setup() fills with information
about the PCM channel setup.
Set the setup structure's channel member to specify the direction. All other members are read-only.
Use the -l asound option to qcc to link against this library.
The snd_pcm_channel_setup() function fills the setup structure with data about the PCM channel's configuration.
- Invalid handle
|Thread||Read the Caveats|
This function is not thread safe if handle (snd_pcm_t) is used across multiple threads.
