This code:

class B {
 protected:
  void Foo(){}
}

class D : public B {
 public:
  void Baz() {
    Foo();
  }
  void Bar() {
    printf("%x\n", &B::Foo);
  }
}

gives this error:

t.cpp: In member function 'void D::Bar()':
Line 3: error: 'void B::Foo()' is protected
  • Why can I call a protected method but not take its address?
  • Is there a way to mark something fully accessible from derived classes rather than only accessible from derived classes and in relation to said derived class?

BTW: This looks related but what I'm looking for a reference to where this is called out in the spec or the like (and hopefully that will lead to how to get things to work the way I was expecting).
