The code relies on the modifier order returned by
cffi:foreign-enum-keyword-list. If this remains the same between CFFI
revisions then, yes. You can see the code below.
(remove nil (loop for key in (cffi:foreign-enum-keyword-list
'sdl-cffi::sdl-mod)
collect (when (>
(logand mod-state
(foreign-enum-value 'sdl-cffi::sdl-mod key))
0)
key)))
Why do you need the results in a particular order?
