Function Pointer & _closure

[nbaztec]

The trouble I'm facing is when I assign a function pointer to another.

Eg:

class foo
{
   public:
      bool (*myFunc)();
};

class Main
{
   public:
      void Procedure();
      bool someFunc();
};

bool Main::someFunc ()
{
   .
   .
}

void Main::Procedure()
{
   foo Obj;
   Obj.myFunc = &someFunc;  //Error
}

On assigning I get the error:
Cannot convert bool(*(_closure)())() to bool(*)(), but I don't know how to fix it. I know that it has something to do with the class owning the function & the function not being accessible without the class object, but how to fix it?

P.S. If the function is a global, then Obj.myFunc = &someGlobalFunc; works out fine

Any help is greatly appreciated.

      bool (*myFunc)();

This is not a pointer to a non-static member function. This is a pointer to a non-class function, or static function.

bool Main::someFunc ()
{
    return true;
}

void Main::Procedure()
{
   foo Obj;
   Obj.myFunc = &someFunc;  //Error
}

Obj.myFunc is a non-static member function. You cannot assign a pointer of a non-static member function to a pointer to a static or non-class function.
