function pointer argument

Hi there, I have a question regarding function pointer n classes. I want to define a member function in a class which has a function pointer in it''s argument list for a function of the same class. Example: class Sample { // The function which gets function addresses void Work(???); // The kind of function i want to pass int Func(DWORD x); } How has Work''s argument list to be done ? Thanks alot for any comment Lorenz
