Sorry i forgot to mention i am working from within a kext here, will i still be able to use that code or is there another way that will let me fulfill my original request since i am coding in a kext How do i cancel a sleep event from happening, along with things like the lid closing and causing a sleep. _______________________________________________ You can only cancel idle sleep, not user initiated sleep (via the power button, the Sleep menu, or closing the lid. int main(int argc, char* argv[]) { IONotificationPortRef portRef; io_object_t notifier; CFRunLoopSourceRef source; powerPort = IORegisterForSystemPower (NULL, &portRef, iokpm_callback, ¬ifier); if (powerPort) { source = IONotificationPortGetRunLoopSource(portRef); CFRunLoopAddSource([[NSRunLoop currentRunLoop] getCFRunLoop], source, kCFRunLoopCommonModes); } [[NSRunLoop currentRunLoop] run]; } static void iokpm_callback (void *myData, io_service_t service, natural_t message, void *arg) { switch(message) { // must always respond to the power state change messages case kIOMessageSystemWillSleep: case kIOMessageCanSystemSleep: // we can't prevent user initiated power off, only idle power off case kIOMessageSystemWillPowerOff: case kIOMessageSystemWillRestart: IOAllowPowerChange(powerPort, (long)arg); break; This email sent to site_archiver@lists.apple.com
