This is a "virtual" function. It is resolved at runtime, i.e. if the object 
actually is a cDvbDevice, the implementation of cDvbDevice is called, if it 
is say a cAnalogDevice the implementation of the function of this class will 
be used.
This is a key concept of object oriented languages, you will have to think 
over it. In Java e.g., all functions are "virtual" in terms of C++.
