Hello.
My problem is about catching shutdown/reboot from KEXT. I wrote kext, added
registerSleepWakeInterest(&mySleepHandler, myself, NULL) where mySleepHandler logs something.
it gets logged when system goes to sleep, but nothing gets logged when I try to restart system.
Here is whole code:
#include <sys/systm.h>
#include <mach/mach_types.h>
#include <IOKit/IOLib.h>
#include <IOKit/pwr_mgt/RootDomain.h>
#include <IOKit/pwr_mgt/IOPM.h>
#include <IOKit/IOService.h>
#include <IOKit/IONotifier.h>
IONotifier *notifier;
extern "C" {
kern_return_t MyKext_start(kmod_info_t * ki, void *d);
kern_return_t MyKext_stop(kmod_info_t *ki, void *d);
IOReturn mySleepHandler( void * target, void * refCon,
UInt32 messageType, IOService * provider,
void * messageArgument, vm_size_t argSize )
{
IOLog("Message type was %d\n", messageType);
acknowledgeSleepWakeNotification(refCon);
return 0;
}
kern_return_t MyKext_start(kmod_info_t * ki, void *d)
{
printf("MyKext has started.\n");
void *myself = NULL; // Would pass the self pointer here if in a class instance
notifier = registerSleepWakeInterest(&mySleepHandler, myself, NULL);
return KERN_SUCCESS;
}
kern_return_t MyKext_stop(kmod_info_t *ki, void *d)
{
printf("MyKext has finished.\n");
return KERN_SUCCESS;
}
}
what's wrong? comment under kIOMessageSystemWillPowerOff says:
* Indicates an imminent system shutdown. Recipients have a limited
* amount of time to respond, otherwise the system will timeout and
* shutdown even without a response.
* Delivered to in-kernel IOKit drivers via <code>IOService::systemWillShutdown()</code>,
* and to clients of <code>registerPrioritySleepWakeInterest()</code>.
* Never delivered to user space notification clients.
