Hi 
Does anyone have experience with InterruptHookIdle ? 

I'm getting errono 22 ( invalid Argument ) when calling this function. 



void Idle(uint64_t * next_idle, struct qtime_entry * qtime)
{


}


then : 
main(int argc, char *argv[])
{

       ThreadCtl( _NTO_TCTL_IO, 0 );
	int ret = InterruptHookIdle(Idle,0);
}
