[cffi-devel] Lisp type for word size

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. -T.
