The function
delete-directory
attempts to delete the directory
directory
. It returns
t
on success, and on failure either returns
nil
or signals an error.
error
determines what happens when
delete-directory
fails. When
error
is
nil
(the default), if
directory
does not exist
delete-directory
returns
nil
, otherwise any failure causes an error to be signaled. If
error
is
:no-error
,
delete-directory
returns
nil
on any failure. If
error
is
:error
, any failure causes an error to be signaled.
Typical reasons for failures in
delete-directory
are that
directory
is not empty, or that the user does not have the right permissions.
