Variable *default-pathname-defaults*

Value Type:

a pathname object.

Initial Value:

I added this first little phrase. -kmp 12-Jan-91An implementation-dependent pathname, typically in the working directory that was current when Common Lisp was started up.

Description:

23.1.2 26a 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.
