How to define a function pointer pointing to a static member function?

Question

#include \"stdafx.h\"

class Person;
typedef void (Person::*PPMF)();

// error C2159: more than one storage class specified
typedef static void (Person::*PPMF2)();           


        

Answer 1

If the function is static it does not require a (implicit) this pointer to be invoked. Therefore, a pointer to a static member function is not the same as a member function pointer:

#include "stdafx.h"

class Person;
typedef void (Person::*PPMF)();
typedef /*static*/ void (*PPMF2)();

class Person
{
public:
    static PPMF verificationFUnction()
    { 
        return &Person::verifyAddress; 
    }
    PPMF2 verificationFUnction2() 
    { 
        return &Person::verifyAddress2; 
    }
private:
    void verifyAddress() {}

    static void verifyAddress2() {}
};

int _tmain(int argc, _TCHAR* argv[])
{
    Person scott;

    PPMF pmf = scott.verificationFUnction();
    (*pmf)();
    return 0;
}

EDIT:

removed the offending static from the typedef.
