namestring pathname => namestring
file-namestring pathname => namestring
directory-namestring pathname => namestring
host-namestring pathname => namestring
enough-namestring pathname &optional defaults => namestring
Arguments and Values:
pathname---a pathname designator.
defaults---a pathname designator. The default is the value of *default-pathname-defaults*.
namestring---a string or nil.
These functions convert pathname into a namestring. The name represented by pathname is returned as a namestring in an implementation-dependent canonical form.
namestring returns the full form of pathname.
file-namestring returns just the name, type, and version components of pathname.
directory-namestring returns the directory name portion.
host-namestring returns the host name.
enough-namestring returns an abbreviated namestring that is just sufficient to identify the file named by pathname when considered relative to the defaults. It is required that
(merge-pathnames (enough-namestring pathname defaults) defaults) == (merge-pathnames (parse-namestring pathname nil defaults) defaults)in all cases, and the result of enough-namestring is the shortest reasonable string that will satisfy this criterion.
It is not necessarily possible to construct a valid namestring by concatenating some of the three shorter namestrings in some order.

;;;Using Unix syntax and the wildcard conventions used by the ;;;particular version of Unix on which this example was created: (namestring (translate-pathname "/usr/dmr/hacks/frob.l" "/usr/d*/hacks/*.l" "/usr/d*/backup/hacks/backup-*.*")) => "/usr/dmr/backup/hacks/backup-frob.l" (namestring (translate-pathname "/usr/dmr/hacks/frob.l" "/usr/d*/hacks/fr*.l" "/usr/d*/backup/hacks/backup-*.*")) => "/usr/dmr/backup/hacks/backup-ob.l" ;;;This is similar to the above example but uses two different hosts, ;;;U: which is a Unix and V: which is a VMS. Note the translation ;;;of file type and alphabetic case conventions.
