C++: Pointer to monomorphic version of virtual member function?

Question

In C++, it\'s possible to get a pointer to a (non-static) member function of a class, and then later invoke it on an object. If the function was virtual, the call is dispatc

Answer 1

To elaborate with a code example for a wrapper function (and despite the fact the OP wanted to avoid this method!) as in many cases this is the pragmatically preferable solution:

#include 
using std::cout; using std::endl;

struct Foo
{
    virtual void foo() { cout << 1 << endl; }
};

struct Foo2: public Foo
{
    virtual void foo() { cout << 2 << endl; }
};

void monomorphicFooFoo( Foo * f ) { f->Foo::foo(); }

int main()
{
    Foo *foo = new Foo2;

    void (*baseFoo)( Foo * ) = &monomorphicFooFoo;
    baseFoo( foo ); // Prints 1
}
