Function References

Question

So I was just working with function pointers and I remembered that you could do this:

void Foo()
{
}

int main()
{
    void(& func)() = Foo;

    func();         


        

Answer 1

I've used them in a plug-in system where plug-in DLLs could be loaded/unloaded at run-time. I would look for known symbols in each DLL and cast them to function pointers.
