Hi all,
QA1340 "Registering and unregistering for sleep notifications" is just
what I was looking for.
<http://developer.apple.com/qa/qa2004/qa1340.html>
I copy and pasted the code from 'listing 1' and put it in a brand new
Xcode 'CoreFoundation tool' project. But the callback function
specified to IORegisterForSystemPower() is never called! I've put a
breakpoint, printf, and assert(0).
Is anyone using this code? I've tried in 10.3.9, 10.4.8, and 9a303 and
it just doesn't seem to work at all.
(PS: yes, I have a good reason to deny sleep: firmware update over RS-232.)
Thanks,
--
