Yes, the second two items overlap. This is correct. This is the MSVC Express string format - Toady appears to be using standard C++ structures pretty much everywhere.

----

I'm currently trying to figure out the internal representation of the new Dwarf Fortress. I'm putting notes here so if someone else wants to start, they can collaborate instead of duplicating efforts.
 +
 
 +
Toady has said that the address to the active-creature vector seems to be 0x01415A00. This is indeed a vector, I haven't verified if it's the right one.
 +
 
 +
Toady's also using MSVC Express. He tends to use vectors and standard strings. MSVC's string is *weird* and I haven't deciphered it yet.
 +
 
 +
Updates as I figure things out. [[User:ZorbaTHut|ZorbaTHut]] 22:10, 29 October 2007 (EDT)
