| Allegro CL version 8.2 Unrevised from 8.1 to 8.2. 8.1 version |
This variable and the variables
*open-rename-suffix*
and *open-rename-function*
work together in renaming a file opened with open
with the direction keyword argument either
:output
or :io
and
the if-exists keyword argument either
:rename
or
:rename-and-delete
. The function that is the initial value of *open-rename-function*
renames the existing file by prepending the value of this variable,
moving the current file type into the filename, and making the value
of *open-rename-suffix*
the new type.
The initial value of this variable is the empty string
"" and that of
*open-rename-suffix*
is the
string "bak". If all three variables have their initial
values, the file foo.txt will be renamed foo.txt.bak
(with filename foo.txt and file type bak).
See Extensions to cl:make-package, cl:disassemble, cl:open in implementation.htm for information on the implementation of open.
