calling "after return"...?

[insert ya favorite greetin' here;-)]

guess you have the following classes...
___________________________________
class  {
  //..a couple of methods ...//
};

class A {
public:
  //...//
  B* GetB() // <- this we'll talk about
private:
  B* m_pB;
};

A::GetB() {
  //..some code..//
  return m_pB;
};
___________________________________

when some does a...

A.GetB()->AMethodOfB();

.... and you want some code be executed before B::AMethodOfB() is
called, you simply pack it into A::GetB()'s body before the return.
But what do yuo do, if you want to execute some code _after_ B's
method is executed, e.g. when the callstack - after completing the
call into B - returns back into A::GetB()?
