## Function Documentation

int _snd_pcm_iec958_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 IEC958 subframe conversion PCM.

Parameters:

  | pcmp | Returns created PCM handle
  | name | Name of PCM
  | root | Root configuration node
  | conf | Configuration node with copy 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_iec958_open | ( | snd_pcm_t ** | pcmp,
|  | const char * | name,
|  | snd_pcm_format_t | sformat,
|  | snd_pcm_t * | slave,
|  | int | close_slave,
|  | const unsigned char * | status_bits,
|  | const unsigned char * | preamble_vals |
| ) |  |  |

Creates a new IEC958 subframe conversion PCM.

Parameters:

  | pcmp | Returns created PCM handle
  | name | Name of PCM
  | sformat | Slave (destination) format
  | slave | Slave PCM handle
  | close_slave | When set, the slave PCM handle is closed with copy PCM
  | status_bits | The IEC958 status bits
  | preamble_vals | The preamble byte values

Return values:

  | zero | on success otherwise a negative error code
