(width (:pointer :int)) (heigh (:pointer :int)) (title (:pointer :char)))

please help.

Yes, :void is correct there. (:pointer :int) should be :int instead and :string should be more convenient than (:pointer :char) since it'll convert Lisp strings to C strings for you. You may find https://common-lisp.net/project/cffi/manual/html_node/Tutorial.html useful.
