2 * fd/win32.cc: support for windows
3 *
4 * this file is noticably more complex than *nix, and that's because
5 * there is no "simple" way to get the paths of a file. In fact, this thing requires
6 * you to use *internal functions* that can't even be linked to, hence why we have to
7 * use GetProcAddress and such. what a mess.
8 *
9 * Speaking of which, because this file uses internal functions of the OS, it is not
10 * even guaranteed to work far into the future. however, just like with macOS, these
11 * things have stayed the same since Vista so if Microsoft *really* wants compatibility
12 * then they're pretty much forced to keeping this the same anyway.
