SND_PCM_HW_CONSTRAIN(9)                      PCM API                      SND_PCM_HW_CONSTRAIN(9)



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.
