GNU C++: can i get the derived class pointer on base class?

[Cambalinho]

i'm on base class. can i get the derived\child class pointer without using it on constructor argument?

You have to explain the goal a bit more.


As is the question makes little sense, because a base class is not supposed to know nor care whether anything derives from it (although abstract classes can bet that something does).

Use dynamic_cast<derived *>(...). See:
