   how to stop in indicated object
  when debug ,I wanna just stop at a bass class function that be called by a special class object other than every derived class object.class A{void p()// debug here};class B : A;class C : A;C *c ; B *b;c->p()//stop hereb->p()//not stop   
  depends on your ide, there are conditional breakpoints that you can prolly work it out with in visual studio
