## Functions

int | snd_pcm_ioplug_create (snd_pcm_ioplug_t *ioplug, const char *name, snd_pcm_stream_t stream, int mode)
| Create an ioplug instance.
int | snd_pcm_ioplug_delete (snd_pcm_ioplug_t *ioplug)
| Delete the ioplug instance.
void | snd_pcm_ioplug_params_reset (snd_pcm_ioplug_t *ioplug)
| Reset ioplug parameters.
int | snd_pcm_ioplug_set_param_list (snd_pcm_ioplug_t *ioplug, int type, unsigned int num_list, const unsigned int *list)
| Set parameter as the list.
int | snd_pcm_ioplug_set_param_minmax (snd_pcm_ioplug_t *ioplug, int type, unsigned int min, unsigned int max)
| Set parameter as the min/max values.
int | snd_pcm_ioplug_reinit_status (snd_pcm_ioplug_t *ioplug)
| Reinitialize the poll and mmap status.
const snd_pcm_channel_area_t * | snd_pcm_ioplug_mmap_areas (snd_pcm_ioplug_t *ioplug)
| Get mmap area of ioplug.
int | snd_pcm_ioplug_set_state (snd_pcm_ioplug_t *ioplug, snd_pcm_state_t state)
| Change the ioplug PCM status.
