		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,
