I don't know the answer either, but I tend to doubt it. You might want to
try
asking this question on the darwin-development mailing list. There are more
people familiar with kext and IOKit development over there.
Thanks, I'll give that a shot.
I would think that the more likely scenario is that you have a kext which
implements the /dev/audio device and starts up a userland daemon process,
which then communicates with the kext via IOUserClient, and this userland
process would make the CoreAudio calls. (Having never done anything like
this, I have no idea if this will work or not.)
That's a good idea. I had initially thought of doing a daemon as well, but
I was unaware of any way to send messages between a kext and the userland
daemon (as you say IOUserClient can). I will have to investigate that
function. I assume by the name that it is a part of IOKit? My current
kernel extension isn't really fancy enough to warrant using the OO
properties of IOKit, do you know if there are any alternative methods?
Thanks a bunch!
