19.2.2.1.2 Case in Pathname Components

Namestrings always use local file system case conventions, but Common Lisp functions that manipulate pathname components allow the caller to select either of two conventions for representing case in component values by supplying a value for the :case keyword argument. The next figure lists the functions relating to pathnames that permit a :case argument:

make-pathname    pathname-directory  pathname-name  
pathname-device  pathname-host       pathname-type
