Does CFFI contain a Lisp type which represents the machine's word size? I guess it could be defined as
(deftype word-size ()
`(unsigned-byte ,(* 8 (foreign-type-size :long))))
Are there any caveats? E.g. what about a 32bit Lisp
implementation on a 64bit architecture?
Perhaps the type should rather be defined in each
backend.
