__super

__super::member_function();

The __super keyword allows you to explicitly state that you are calling a base-class implementation for a function that you are overriding. 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.

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)
}
};

int main() {
}
