PROBE-FILE
PROBE-FILE
cannot be used to check whether a directory exists.
Use functions EXT:PROBE-DIRECTORY
, EXT:PROBE-PATHNAME
or DIRECTORY
for this.
FILE-AUTHOR
FILE-AUTHOR
always returns NIL
, because the operating systems
CLISP is ported to do not store a file's author in the file system.
Some operating systems, such as UNIX, have the notion of a file's
owner, and some other Common Lisp implementations return
the user name of the file owner. CLISP does not do this, because
owner and author are not the
same; in particular, authorship is preserved by copying, while
ownership is not.
Use OS:FILE-OWNER
to find the owner of the file. See also
OS:FILE-PROPERTIES
(Platform Dependent: Win32 platform only.).
DELETE-FILE
(
deletes the pathname
DELETE-FILE
pathname
)pathname
, not its TRUENAME
, and returns the absolute pathname it
actually removed or NIL
if pathname
did not exist.
When pathname
points to a file which is currently open in CLISP,
an ERROR
is SIGNAL
ed.
To remove a directory, use EXT:DELETE-DIRECTORY
instead.
RENAME-FILE
This functions accepts and extra keyword argument :IF-EXISTS
.
When it is :ERROR
(the default), an ERROR
is SIGNAL
ed if the destination
pathname names an existing file, otherwise (e.g., if it is :OVERWRITE
)
the destination file atomically overwritten.
When CUSTOM:*ANSI*
is non-NIL
, only the standard two arguments are accepted,
and and ERROR
is SIGNAL
ed when the destination pathname names an existing file.
This function cannot operate on directories,
use EXT:RENAME-DIRECTORY
to rename a directory.
