Hmm. I tried to track this alleged removal, unsuccessfully. :-) Are you sure you didn't add that code yourself? I can't find this code in either 0.9.0 or 0.9.1. In any case, you bring up a good point, which I've mentioned before too: <http://article.gmane.org/gmane.lisp.cffi.devel/1033> Using the cffi-newtypes branch (which I hope to merge soon, since there haven't been any complaints, unless James has any objections), you could do something like this: (defcstruct %my-struct ...) (define-foreign-type my-struct-type () () (:actual-type %my-struct) (:simple-parser my-struct)) (defmethod translate-from-foreign (value (type my-struct-type)) ...) (defmethod translate-to-foreign (value (type my-struct-type)) ...) (defmethod free-translated-object (value (type my-struct-type) param) ...) Now, perhaps defcstruct could take an option to define a type class thus avoiding the need to define a wrapper type. Perhaps something like this? (defcstruct (my-struct :class my-struct-type) ...) Any comments? -- Luís Oliveira http://student.dei.uc.pt/~lmoliv/ _______________________________________________ cffi-devel mailing list [EMAIL PROTECTED] http://common-lisp.net/cgi-bin/mailman/listinfo/cffi-devel
