Function Pointer Question

Virtual functions are implemented on on the base of vtables, which in 
turn are implemented using function pointers.
So it would be good to get a grasp on functionpointers (they exist in 
C++ as well), also I believe this is not a C mailing list, take a look 
at stackoverflow or a c/c++ site or book of your choice.
If you know how a pointer works, you will find it easy to understand how 
a functionpointer works.
