partial example of global keyboard event handler

example.cpp

void *EventLoop(void *args)
{
	int state;
    pthread_setcancelstate (PTHREAD_CANCEL_ENABLE, &state);
    pthread_setcanceltype (PTHREAD_CANCEL_ASYNCHRONOUS, &state);

	// In one thread run the event loop to get hotkey presses
	EventHotKeyID gMyHotKeyID1, gMyHotKeyID2;
    EventTypeSpec eventType;
       
	/* Register event handler for hotkeys */
	eventType.eventClass=kEventClassKeyboard;
    eventType.eventKind=kEventHotKeyPressed;
    InstallApplicationEventHandler(NewEventHandlerUPP(MyHotKeyHandler),1,&eventType,NULL,NULL);


	/* Register the hotkeys */

	/* Regular F1-F12=F(fkey)*/
	gMyHotKeyID1.signature='gc01';
	gMyHotKeyID1.id=1;
    	RegisterEventHotKey(fnkeyTable[Typer::getInstance()->getFKey()], 0, gMyHotKeyID1, GetApplicationEventTarget(), 0, &gMyHotKeyRef1);

	/* Also register for shift F8 -- 0x64 == F8, 56 == Shift */
    gMyHotKeyID2.signature='gc02';
    gMyHotKeyID2.id=2;
    RegisterEventHotKey(fnkeyTable[Typer::getInstance()->getFKey()], shiftKey, gMyHotKeyID2, 	GetApplicationEventTarget(), 0, &gMyHotKeyRef2);

	
	// Run the event loop
    
    EventTargetRef target = GetEventDispatcherTarget();
    while(1) {
        EventRef event;	  
		if (ReceiveNextEvent(0, NULL, (kEventDurationSecond / 10), true, &event) == noErr) {
			SendEventToEventTarget (event, target);
			ReleaseEvent(event);
		}
        pthread_testcancel();
    }
//    RunApplicationEventLoop();

    pthread_exit(0);
    
}

Hi there does this work from a thread? Becase I am trying to just do InstallApplicationEventHandler and RegisterEventHotKey from a spawned thread but it keeps crashing.
