This C code (you don't show the declarations for tidyCreate() and tidySaveBuffer() though) translates to something like this: (use-package :cffi) (defcstruct tidy-buffer ...) (defctype tidy-doc :pointer) ; if you prefer... (defcfun ("tidyCreate" tidy-create) :tidy-doc) (defcfun ("tidySaveBuffer" tidy-save-buffer) :void ;;? (doc tidy-doc) (out tidy-buffer)) ;; caller (with-foreign-object (output tidy-buffer) (let ((tdoc (tidy-create))) (tidy-save-buffer tdoc output))) HTH -- Luis Oliveira luismbo (@) gmail (.) com Equipa Portuguesa do Translation Project http://www.iro.umontreal.ca/translation/registry.cgi?team=pt
