Constructor & Destructor Documentation

CTraceRoute::CTraceRoute	(	TR_CALLBACK	pCallback = NULL,
		DWORD	dwUserParm = 0
	)

3/1/97 Richard Bross

Call back function and user parm. User parm is passed to the callback. Typically it is a pointer to the calling object, since the callback must be static.
