It's possible if you pass an actual test instance to your static function. — Crowman

This is not possible. Static member functions can only access static class members. This makes sense, too, if you consider that you can invoke

test::test();

without instantiating an object. In fact, when executing the code above there may not even be a single class instance.

If you need to access non-static class members from a static member function you need to pass a class instance to it, either a pointer or a reference. When you're doing that, however, you might as well make the static member function non-static.

You can't do that. When you use a static function, you are in static context. Only static members may be accessed, the others don't exist.
