hi all.


Is there have some limitation on the parameter size of the interface: 


snd_pcm_sframes_t snd_pcm_readi(snd_pcm_t *pcm, void *buffer,
snd_pcm_uframes_t size)?


should be the SIZE as any value ? For example, set the size <
period_size, ok?


does the parameter depend on the period_size?              


Thanks a lot.
