# `__super`

**Microsoft Specific**

Allows you to explicitly state that you are calling a base-class implementation for a function that you are overriding.

## Syntax

```
__super::member_function();
```

## Remarks

All accessible base-class methods are considered during the overload resolution phase, and the function that provides the best match is the one that is called.

**`__super`** can only appear within the body of a member function.

**`__super`** cannot be used with a using declaration. See [using Declaration](../cpp/using-declaration.md) for more information.

With the introduction of [attributes](../windows/attributes/attributes-alphabetical-reference.md) that inject code, your code might contain one or more base classes whose names you may not know but that contain methods that you wish to call.

## Example

```cpp
// deriv_super.cpp
// compile with: /c
struct B1 {
   void mf(int) {}
};

struct B2 {
   void mf(short) {}

   void mf(char) {}
};

struct D : B1, B2 {
   void mf(short) {
      __super::mf(1);   // Calls B1::mf(int)
      __super::mf('s');   // Calls B2::mf(char)
   }
};
```
