*default-pathname-defaults* (Variable)

Value Type:

a pathname object.

Initial Value:

An implementation-dependent pathname, typically in the working directory that was current when Common Lisp was started up.

Description:

a pathname, used as the default whenever a function needs a default pathname and one is not supplied.

Examples:
 ;; This example illustrates a possible usage for a hypothetical Lisp running on a
 ;; DEC TOPS-20 file system.  Since pathname conventions vary between Lisp
 ;; implementations and host file system types, it is not possible to provide a
 ;; general-purpose, conforming example.
 *default-pathname-defaults*  #P"PS:<FRED>"
 (merge-pathnames (make-pathname :name "CALENDAR"))
 #P"PS:<FRED>CALENDAR"
 (let ((*default-pathname-defaults* (pathname "<MARY>")))
   (merge-pathnames (make-pathname :name "CALENDAR")))
 #P"<MARY>CALENDAR"
Affected By:

The implementation.
