int _snd_pcm_multi_open (  snd_pcm_t **  pcmp, const char *  name, snd_config_t *  root, snd_config_t *  conf, snd_pcm_stream_t  stream, int  mode )

Creates a new Multi PCM. Parameters: pcmp  Returns created PCM handle name  Name of PCM root  Root configuration node conf  Configuration node with Multi PCM description stream  Stream type mode  Stream mode Return values: zero  on success otherwise a negative error code Warning: Using of this function might be dangerous in the sense of compatibility reasons. The prototype might be freely changed in future.

int snd_pcm_multi_open (  snd_pcm_t **  pcmp, const char *  name, unsigned int  slaves_count, unsigned int  master_slave, snd_pcm_t **  slaves_pcm, unsigned int *  schannels_count, unsigned int  channels_count, int *  sidxs, unsigned int *  schannels, int  close_slaves )

Creates a new Multi PCM. Parameters: pcmp  Returns created PCM handle name  Name of PCM slaves_count  Count of slaves master_slave  Master slave number slaves_pcm  Array with slave PCMs schannels_count  Array with slave channel counts channels_count  Count of channels sidxs  Array with channels indexes to slaves schannels  Array with slave channels close_slaves  When set, the slave PCM handle is closed Return values: zero  on success otherwise a negative error code Warning: Using of this function might be dangerous in the sense of compatibility reasons.
