I'm working on a software synth, my first project with ALSA. Everything
is going fine, save for the initialization of the PCM output: based on
the scraps of documentation I've found, I have not been able to figure
out what exactly a "period" is, what its size signifies and how the
concept relates to or overlaps with that of output buffering.

For an example, suppose I'm producing 44100 hz 16-bit mono signal and
want a 256-frame (512 bytes) output buffer. How do I use the period-related
hw functions in this case?
