What I suggest here is that it would be better to declare your strings as
arrays rather than pointers. If you use pointers, you must make sure that
your strings are still valid at that pointer location when you want to use
them. If you use arrays, you could simply use MemMove to copy the string
contents into your struct.

Yup.

Well, you could. But that would make things more complicated right? You'll
need to lock down the handle when you want to use the string, and you'll
need to free the handle when your strings are no longer in use. I think it's
better to declare them as char arrays. :)

We all have our first. :)
