[alsa-devel] snd_pcm_sw_params_set_xfer_align replacement?

snd_pcm_sw_params_set_xfer_align() has been deprecated but the docs don't mention what it was replaced with.

I don't ever want or need partial reads and writes -- my app would actually be happiest being completely synchronous to the hardware with fixed-size buffers. any suggestions how to get ALSA to do this?
