up/downcast with shared_ptr?

[.rhavin grobert]

guess you have the following:

class AA;
class A {
shared_ptr<AA> m_a;
};

class BB: public AA;
class B {
shared_ptr<BB> m_a;
};

void g(B* pB);

void f(A* pA) { <-- called with a B*
// i need to call g() here //
};

what would be the best way to do this?

You're working with raw pointers here, not the shared_ptr. Do it like
you normally would.

If you where working with shared_ptrs you would use the pointer casts
documented in the boost documentation.
