I wrote a cross platform directory reading library. So far it works
with Visual C++ and Gnu C, though it whould work with any C compiler
that can use either the windows _find* set of functions or the
standard *dir set of functions (opendir, readir, etc). The latter may
need a #ifdef change in KG_FileSys.c though.
I thought it appropriate to post a message about it to this list
because.
1.) A lot of people ask how to do this here.
2.) I’ve needed this code in many of my own projects.
3.) It’s simple, low level, and cross platform, just like SDL 
Anyway, it lives here:

(Off to write my next mini library to better the indie SDL Gamedev’rs
lives)
