Compiler Warning (level 4) C4263

Error Message

'function' : member function does not override any base class virtual member function

A class function definition has the same name as a virtual function in a base class but not the same number or type of arguments. This effectively hides the virtual function in the base class.

This warning is off by default. See Compiler Warnings That Are Off by Default for more information.

The following sample generates C4263:

// C4263.cpp
// compile with: /W4
#pragma warning(default:4263)
#pragma warning(default:4264)
class B {
public:
   virtual void func();
};

class D : public B {
   void func(int);   // C4263
};

int main() {
}
