int _snd_pcm_rate_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 rate PCM. Parameters: pcmp  Returns created PCM handle name  Name of PCM root  Root configuration node conf  Configuration node with rate 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.

const char* snd_pcm_rate_get_default_converter (  snd_config_t *  root  )

Get a default converter string. Parameters: root  Root configuration node Return values: A  const string if found, or NULL

int snd_pcm_rate_open (  snd_pcm_t **  pcmp, const char *  name, snd_pcm_format_t  sformat, unsigned int  srate, const char *  type, snd_pcm_t *  slave, int  close_slave )

Creates a new rate PCM. Parameters: pcmp  Returns created PCM handle name  Name of PCM sformat  Slave format srate  Slave rate type  SRC type string slave  Slave PCM handle close_slave  When set, the slave PCM handle is closed with copy PCM Return values: zero  on success otherwise a negative error code Warning: Using of this function might be dangerous in the sense of compatibility reasons.
