Power Management API for auto-wake in OSX?

Hey, I need to write a program for OSX that will cause my macbook pro to wake up after a certain amount of time of sleeping. SleepX is almost perfect for me, but I want it to only go back to sleep if noone is moving the mouse/hitting the keyboard, etc.... I tried using the approac开发者_StackOverflow社区h in the "wakeFromSleep" example in the Mac power management DDK, but it was unable to find the "Power Management Unit" in my computer, so obviously SleepX is using a different method than the DDK.

Does anyone have any ideas on where I can look to find this API that SleepX is using? Does anyone have suggestions on what software I could use to achieve the end result?

Thank you!

One place to start looking is

nm /Developer/Applications/Utilities/SleepX.app/Contents/MacOS/SleepX

the following lines look relevant

     U _IOAllowPowerChange
     U _IONotificationPortGetRunLoopSource
     U _IOPMSchedulePowerEvent
     U _IORegisterForSystemPower

which in turn come from IOPMLib.h

The pmset command makes it easy to schedule wakeups:

pmset schedule wake "07/04/09 20:00:00"

You want IOPMSchedulePowerEvent.
