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

by

It’s possible in GCC, but the way it’s documented in C++ language extensions section suggests there’s no portable way to do it.

You can do two things:

  1. If you control the class, create a non-virtual function and a virtual wrapper for it and when you know you don’t need virtual dispatch, just take address of the non-virtual one.
  2. If you don’t, create a template functor that will hold the member pointer and do the explicit scope call.
