probe-directory

Arguments: pathspec

This function tests whether pathspec exists and is a directory, returning the result of applying truename to pathspec if it is, and returning nil if it does not exist or is not a directory. pathspec should be a pathname, a string naming a pathname, or a stream open to a file, that is, the argument should be a standard Common Lisp pathname designator.

Examples

;; Assume a directory /tmp exists:

(probe-directory "/tmp/") RETURNS #p"/tmp/"
(probe-directory "/tmp/foo.cl") RETURNS nil
  ;; (whether or not /tmp/foo.cl exists)

See probe-file and pathnames.htm.
