Inheriting pointers in derived class

[Buzzyous]

Hello to all.

I write you after many years, got rusty, even more than then, on inheritances.

I will pose a simplified version of the problem i have, to go straight to the point.
I have a base class, baseclass, which has three public members, pointers to baseclass class; they are links in a node structure, and are protected for access security reason.
I have a function that retrieves these pointers, GetPtr, parametrized on the pointer to get (in the full program, there is a dynamic allocated array of pointers). This function is publicly accessible

class baseclass
{
//...
protected: 
baseclass *ptr1, *ptr2, *ptr3;

public:
baseclass* GetPtr(unsigned char numeral);

//...
}

The problem is, when I derive a class from baseclass, let's say derivedclass, and call GetPtr() I obviously retrieve the pointer to the baseclass, while I need to obtain an inherited version of GetPtr that returns the correct derived class pointer type.

I could define GetPtr as virtual and override it in all derived classes, but theese can be very numerous, and this doesn't solve my problem.

Is there a way to achieve this goal (I think dynamic cast could help, but is it dangerous?)?

Thanks you all in advance!
