Description attila 2016-01-01 16:53:41 UTC 
i'm working on a Common Lisp FFI for libsdl, and the whole thing is mostly automatically generated (https://github.com/attila-lendvai/hu.dwim.sdl).

on the lisp side i have introduced a type that upon ffi->lisp conversion automatically signals an error if the return value is negative, but right now i would need to list every function by hand where it applies. unfortunately not all int return values are error codes.

if there was something along the lines:

typedef SDL_ErrorCode int;

and it was used to mark the functions that return an error code, then the lisp FFI could automatically translate that type. please consider adding this!

That seems like a good change for SDL 2.1
