In C++ is not possible to declare a static virtual function, neither cast a non-static function to a C style function pointer.

Now, I have a plain ol' C SDK that uses function pointers heavily. 

I have to fill a structure with several function pointers. I was planning to use an abstract class with a bunch of static pure virtual methods, and redefine them in derived classes and fill the structure with them. It wasn't until then that I realized that static virtual are not allowed in C++.

Also this C SDKs function signature doesn't have a userData param.

Is there any good alternative? The best I can think of is defining some pure virtual methods GetFuncA(), GetFuncB(),... and some static members FuncA()/FuncB() in each derived class, which would be returned by the GetFuncX(). Then a function in the abstract class would call those functions to get the pointers and fill the structure.

**Edit**
Answering to John Dibling, it would be great to be able to do this:

```
class Base
{
    FillPointers() { myStruct.funA = myFunA; myStruct.funB = myFunB; ...}
private:
    CStruct myStruct;
    static virtual myFunA(...) = 0;
    static virtual myFunB(...) = 0;
};

class Derived1 : public Base
{
    Derived1() {  FillPointers();  }
    static virtual myFunA(...) {...};
    static virtual myFunB(...) {...};
};

class Derived2 : public Base
{
    Derived2() {  FillPointers();  }
    static virtual myFunA(...) {...};
    static virtual myFunB(...) {...};
};

int main()
{
    Derived1 d1;
    Derived2 d2;
    // Now I have two objects with different functionality
}

```
