Good day,

I would like to receive machine sleep and wake notifications in my daemon.  In 
my Cocoa GUI application, I was able to easily follow the sample code under 
Listing 1 on the page 
<https://developer.apple.com/library/mac/qa/qa1340/_index.html>, but when I 
tried the same approach in my daemon, I received no errors or warnings from 
Xcode or in the system console, and yet the handlers also did not fire.  After 
poking around for a while, I have a hunch that it may have something to do with 
the main event queue not being the same (or existing at all?) in a non-Cocoa 
GUI application.

Is it possible to have a Cocoa-style event queue in a daemon, or is there 
another way to receive machine sleep and wake notifications from the OS in a 
daemon?

Thanks,
- Andrew Keller
