Reference to a pointer of another type

[Joeman]

I am confused about what you mean, but how about

class A{};
class B : public A{};

int main()
{
  A* pA = new B;
  B& pB1 = static_cast<B&>(*pA);
}

and with *& as an example

class A{};
class B : public A{};

int main()
{
  A* pA = new B;
  B* pB1 = static_cast<B*>(pA); 
  B*& pB2 = pB1; 
}
