I figured as much when looking at the duplicate functions.

I guess what I need to know is what is expected in and out of some
of these functions and the best description I get is the existing X code.

Sometimes the data in  is just a void * like in the _ioproc function for 
keyboard.c... It's immediately handled through a Keyboardctl pointer though
so that's not so bad.

I've already done a copy of all the x11-*.c to sdl-*.c and am working on those.
