Referencing the member function "l" in the below example should
not be allowed. The friend relationship that "A" has to "C" is
not inherited in "B" (see 11.4 P8).
class A {
public:
void l();
friend class C;
};
class B : protected A {
};
class C {
void v(B * g) { g->l(); }
};
class C {
void v(B * g) {
g->l(); // Error -- referencing member in B,
// or cast to base and reference in A,
// which is the same as the following:
(static_cast<A *>(g))->l(); // Error -- can't cast to protected base
((A *)g)->l(); // Okay -- old-style cast ignores access
A *p;
p->l(); // Okay -- referencing member in A
}
};
