Information about mixer routes
typedef struct snd_mixer_routes_s
{
int32_t routes, routes_size, routes_over;
uint8_t zero[4]; /* alignment -- zero fill */
snd_mixer_eid_t *proutes;
void *pzero; /* align pointers on 64-bits --> point to NULL */
uint8_t reserved[128]; /* must be filled with zero */
} snd_mixer_routes_t;
The snd_mixer_routes_t structure describes all of the routes
in a mixer.
You can fill this structure by calling
snd_mixer_routes().
|
We recommend that you work with mixer groups instead of manipulating the
elements directly. |
The members of the snd_mixer_routes_t structure include:
- routes
- The total number of routes in the mixer.
- routes_size
- The size of this storage location in
sizeof( snd_mixer_eid_t ) units (i.e. the number of entries
in the proutes array).
Set this member before calling snd_mixer_routes().
- routes_over
- The number of routes that couldn't be copied to the storage location.
- proutes
- NULL, or an array of
snd_mixer_eid_t
structures.
If proutes isn't NULL,
snd_mixer_routes() stores the route IDs in the array.
