  For a Windows binding you almost certainly want 'access, not 'address.
(Though System.Address_To_Access_Conversions can interconvert the two.)

 return Obj'access;
 return Array(5)'access;
If you get accessibility level errors, the compiler is telling you
that you are creating a pointer that may outlive what it's pointing to.
If you're sure what you are doing is safe, you can
  return Obj'unchecked_access;
etc.  You'll see a lot of that in Ada code accessing Windows' API.
