*default-pathname-defaults*

∗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.
