I know. But ALSA hides that in a library, so you never have to deal
with these ugly details. Ain't that great?
OTOH OSS' programmers interface *is* the ioctls themselves. And that's
one reason why its API sucks.
Also, OSS is practically not virtualizable. (LD_PRELOAD and CUSE are
hacks, that only work for the smallest part) The timing model is
broken. The entire design is hardware-specific, and focusses on hw we
had 20 years ago.
OSS as an API is terrible.
