Export low-level cffi functions?

[jfaz1]

Hello! I'm using this library for one of my projects, as well as attempting to make an SDL3 frontend for lem. In order to avoid unnecessary consing/gc pressure, I use the underlying cffi functions and structs directly a lot of the time. I think the % prefix is already good enough indicator that it's the low-level cffi version without needing to make them private. The only inconsistency I find is that cffi slots don't have the % prefix, but the functions do. That's a minor issue though.

Do you think it would make sense to export them alongside the high level functions? I can make these changes.

sure, you can make these changes.

For the slots I think we can add the %prefix. That way the class accessors and cffi struct have same name and thus we don't need to export extra symbols for the slots.

E.g. (sdl3:%w surface1 ) would work on lisp class and (cffi:foreign-slot-value surface2 '(:struct sdl3:surface) 'sdl3:%w) would access the cffi struct.

And since the defcstruct's haven't been exported so far changing their slot names doesn't break the current api.

You'll need to update the translate-to-foregin and translate-from-foreign functions.
