Information about all elements in a mixer
typedef struct snd_mixer_elements_s { int32_t elements, elements_size, elements_over; uint8_t zero[4]; /* alignment -- zero fill */ snd_mixer_eid_t *pelements; void *pzero; /* align pointers on 64-bits; point to NULL */ uint8_t reserved[128]; /* must be filled with zeroes */ } snd_mixer_elements_t;
The snd_mixer_elements_t structure describes all the elements in a mixer. You can fill in this structure by calling snd_mixer_elements().
The members of the snd_mixer_elements_t structure include:
If pelements isn't NULL, snd_mixer_elements() stores the mixer element IDs in the array.
