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.
