Have you tried to reproduce this on clean install of OS X? You can always open a bug with Apple, attach your sample code and see what they think. No matter how your app terminates, if you leave dangling resources they will be cleaned up for you by the kernel. There may be a few exceptions, but Mach ports (which is what IOKit handles are) are not one of them. I thought as much, but it seems strange to me that in this case, the computer will no longer go to sleep due to being idle. I've tested it with a simple terminal program. If I interrupt the run loop (^C for example or SIGTERM) and don't call IODeregisterForSystemPower() the computer simply will not sleep again until it's been rebooted. If anyone else could test this, I'd really appreciate it... it seems like a bug but I only have my hardware at the moment to test on and there may be something wrong with that.

I was wondering if anybody knows... if an application registers for user-level power events and never calls IODeregisterForSystemPower on the notifier and/or IOServiceClose on the root port, does that application then keep the computer from properly handling idle sleep requests? In this case, clean up isn't called because the application terminates unexpectedly for some reason, but I've noticed that once this happens the computer will never sleep due to being idle again. I'm asking on the list because I'm not sure if this is 1) a bug; 2) expected behavior; or 3) something limited to my machine. Has anyone experienced anything like this before?

If it's a character or block special device, look at the major and minor fields of the st_dev and match them to a device in /dev. The file that matches the major/minor fields is /dev/ttysSOMETHING (e.g. /dev/ttys005). But opening it and using it with CFFileDescriptorCreate still doesn't work, i.e. the callback is not called when standard input is readable. This email sent to site_archiver(a)lists.apple.com
