ANSI Common Lisp 19 Filenames 19.1 Overview of Filenames
19.1.1 Namestrings as FilenamesA namestring is a string that represents a filename.In general, the syntax of namestrings involves the use of implementation-defined conventions, usually those customary for the file system in which the named file resides. The only exception is the syntax of a logical pathname namestring, which is defined in this specification; see Section 19.3.1 Syntax of Logical Pathname Namestrings. A conforming program must never unconditionally use a literal namestring other than a logical pathname namestring because Common Lisp does not define any namestring syntax other than that for logical pathnames that would be guaranteed to be portable. However, a conforming program can, if it is careful, successfully manipulate user-supplied data which contains or refers to non-portable namestrings. A namestring can be coerced to a pathname by the functions pathname or parse-namestring.
