Name
snd_pcm_hw_constraint_msbits —
add a hw constraint msbits rule
Synopsis
int snd_pcm_hw_constraint_msbits ( | struct snd_pcm_runtime * runtime, |
| | unsigned int cond, |
| | unsigned int width, |
| | unsigned int msbits); |
Arguments
runtime
PCM runtime instance
cond
condition bits
width
sample bits width
msbits
msbits width
Description
This constraint will set the number of most significant bits (msbits) if a
sample format with the specified width has been select. If width is set to 0
the msbits will be set for any sample format with a width larger than the
specified msbits.
Return
Zero if successful, or a negative error code on failure.
