You get partial reads/writes only when you ask for it (by using non- blocking mode) or when an error occurs.
I want non-blocking behavior (return immediately if there is no data available), but I don't want to have to deal with partial reads. I figured out a workaround using snd_pcm_avail_update(), but I'm wondering if there isn't a better way.
You could write your own read function that calls snd_pcm_read*() repeatedly until you have as much data as you want, but this is probably more complex than just checking for data before doing a blocking read.
