It's modeled very similarly to the stdio API, which is widely documented.

You probably don't need to worry about the file functions. You should
create an 8-bit SDL surface using the SDL_CreateRGBSurface() function,
and then copy the palette information into an array of SDL_Color structs
and set the palette of the surface with SDL_SetColors().
Try asking on the IRC channel if you need more help, or on the mailing
list if nobody is around.
