Subject: Re: question From: Erik Naggum <erik@naggum.no> Date: 1996/08/19 Newsgroups: comp.lang.lisp Message-ID: <3049468439575921@arcana.naggum.no> Bob Green asks for a function that returns the number of arguments of a function. since the number of valid arguments is not a single number for most of the functions worth asking this question, Common Lisp does not provide one. however, the lambda list is usually available, one way or the other. ANSI Common Lisp provides `function-lambda-expression', the documentation of which you will find at http://www.harlequin.com/books/HyperSpec/Body/fun_function-_a-expression.html #\Erik -- life is hard and then you post.
