                                        snd_pcm_hw_param_t var,
                                        const struct snd_pcm_hw_constraint_ranges * r);

ARGUMENTS
       runtime
           PCM runtime instance

       cond
           condition bits

       var
           hw_params variable to apply the list of range constraints

       r
