| Allegro CL version 8.2 Unrevised from 8.1 to 8.2. 8.1 version |
Arguments: directory &key (if-does-not-exist :error) (quiet t) force
The new :osi
module (see Operating System
Interface Functionality in
os-interface.htm), released after the release of
Allegro CL 6.2, has new operators relating to directory and file
manipulation. This symbol naming this function,
delete-directory-and-files
has also been exported
from the excl.osi
package. The new operators are
described in OSI file handling functionality in
os-interface.htm.
With the addition of the new :osi
module, this
function was changed: the force keyword argument
has been added; the default value of the quiet
keyword argument is now t
; and the default
value of the if-does-not-exist keyword argument
is now :error
.
Delete all the files in directory and all
subdirectories of directory.
directory itself is also removed. If
if-does-not-exist is :ignore
then no
error will be signaled if directory does not
exist. Its default is :error
which causes an error
to be signaled on failure. If quiet is nil
, then informative text about the operations
performed is printed. quiet defaults to t
.
On Windows, the force keyword can be used to remove filespec when it is read-only. On UNIX, this is the default behavior so force is effectively ignored.
See also os-interface.htm for general information on the interface between Allegro CL and the operating system. See section Filesystem manipulation functions in that document for information on file and directory information and manipulation functions in Allegro CL.
