How does this work with anonymous enums? E.g. like this (C code) :
enum { SDL_NOEVENT = 0,
SDL_ACTIVEEVENT,
SDL_KEYDOWN,
SDL_KEYUP,
};
#define SDL_EVENTMASK(X) (1<<(X))
enum {
SDL_ACTIVEEVENTMASK = SDL_EVENTMASK(SDL_ACTIVEEVENT),
SDL_KEYDOWNMASK = SDL_EVENTMASK(SDL_KEYDOWN),
SDL_KEYUPMASK = SDL_EVENTMASK(SDL_KEYUP),
};
setEventMask(SDL_ACTIVEEVENTMASK | SDL_KEYUPMASK);
How would you translate this to Lisp with CFFI? With my def-anon-emum macro,
which translates just to defconstant, it would be easy, but perhaps there
are better ways to do it.
