Hi,

I need to find out if my daemon was launched after a restart or during the normal install. Basically I need to now if a machine was restarted. I thought IORegisterForSystemPower would do this but I do not get the kIOMessageSystemWillRestart message.

Here is my code that registers for the notification.

gRootPort=IORegisterForSystemPower (0,&notify,SystemPowerChangedCallback,&anIterator); if (gRootPort) CFRunLoopAddSource(CFRunLoopGetCurrent (),IONotificationPortGetRunLoopSource(notify),kCFRunLoopDefaultMode);

I do get kIOMessageCanSystemSleep when the system is put to sleep.

It could be that my daemon gets killed before I get the kIOMessageSystemWillRestart message.

Is there a better way to find out if the machine is restarted?

Thanks,

Martin
