Where does SDL get the defaults it uses if passed t for :defaults? (Are
these system defaults for are the just arbitrarily chosen by SDL?)
Is there be any way to write the function such that you don't have to pass
dummy values when you want to use the defaults? Currently if you want to use
the default values you have to do something like (sdl:enable-key-repeat 0 0
t). Perhaps you could do something like the following:
(defun example (&optional repeat interval)
(cond
((and repeat interval) (sdl:enable-key-repeat repeat interval))
(repeat (sdl:enable-key-repeat repeat
sdl-cffi::sdl-default-repeat-interval))
(t (sdl:enable-key-repeat 0 0 t))))
Thanks.
