How to add a handle to PALM App event loop with pol?

[Andy yuan]

I am developing Receiving sms software with Pol,and I want to get sms 
content from GSM background,to let users feel nothing interrupt. 

before i use pol,i added a handle to PALM APP EVENT LOOP,i write like this,
startapp.h:
void EventLoop(EventType event);
so:
in startapp.cpp as follows:
void  CStarterApp::EventLoop(EventType event)
{
 do {
     readSms();       //this is my own "background" Handle procedure 
     EvtGetEvent(&event, evtWaitForever);
     if (! SysHandleEvent(&event))
         if (! MenuHandleEvent(0, &event, &error))
             if (! ApplicationHandleEvent(&event))
                 FrmDispatchEvent(&event);
 } while (event.eType != appStopEvent);
}

but it's error!
Error   : undefined identifier 'ApplicationHandleEvent'
StarterApp.cpp line 485 if (!ApplicationHandleEvent(&event))
why?


in pol,how can i add my readsms() procedure to system event loop?
or there is another way to implement?
Thank you very much in advance!
