Detailed Description
A simple c++ application example.
ra_appl is a subclass to rt_appl and implements the virtual functions open(), close(), and scan().
The open function fetches pointer to the digita value object Dv1 and Dv2, and to the alalog value object Av1. It also connects to the message handler.
The scan function is called cyclically and sets one value to Av1 if Dv1 is high and another value if Dv1 is low. When Dv2 goes high an alarm is sent.
The close function unreferences the fetched pointers.
