  8. Let's suppose that I keep a pointer to an object, foo, in a class that I am
  9. archiving:
  10.  
  11. class FW_CLASS_ATTR CoolStuff
  12. {
  13.    MyClass *foo;
  14.         etc
  15. }
  16.  
  17. When I write this CoolStuff out to the archive, it looks something like this:
  18.  
  19. void CoolStuff::Flatten( FW_CWritableStream& archive )
  20. {
  21.    FW_WRITE_DYNAMIC_OBJECT( archive, foo, MyClass );
  22. }
  23.  
  24.  
  25. What happens if foo is NULL?  Will FW_READ_DYNAMIC_OBJECT recognize it as such?
