I'm trying to send a email notification to the user from my Facebook application. I'm trying to use the FaceBook JavaScript API function

notifications_sendEmail(Array recipients,  String subject,  String text,  String fbml,  Object onRequestCompleted)

I can understand the first four parameters. But what's the usage of the last parameter 'onRequestCompleted'. The Doc says it's the call back function. But, what if I do not want to execute a call back function? In this case, what will be a valid values to the parameter onRequestCompleted?
