Variable *DEFAULT-PATHNAME-DEFAULTS*

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.
