Agreed with Corona, and I was going to make the same statement, but not seeing the rest of the code, and under the assumption it works, I figured maybe it was memory mapping the file to some fixed address location. That'd allow the pointer values to be stored and actually work so long as they only pointed to an address within the memory mapped region.

That said, I have no idea if the code is actually doing this. And, I must admit, for a properties file it's fetched.

As for the OP, I think you're generally misguided regarding what the code is doing. That struct is unlikely to be stored directly in the file. I'd dig a little deeper in the code and figure out what is reading and writing the file's data.

Better, why don't you just post what the file looks like; with that information we could probably immediately tell you whether or not that exact structure is stored verbatim in the file.
