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.
