How to overload operator==() for a pointer to the class?

Question

I have a class called AString. It is pretty basic:

class AString
{
public:
    AString(const char *pSetString = NULL);
    ~AString();
    bool

As pointed out by Oli Charlesworth, in a comment below, this is impossible.

You would need to define an operator like

   bool operator==(const AString *as, const char *cs); // Note: C++ will not do that

but you cannot overload an operator unless one of its parameters is non-primitive type - and pointers (both pointers to AString and pointers to char) are primitive types.
