|
|
.Sh DESCRIPTION
|
|
The
|
|
.Fn acl_delete_def_file ,
|
|
.Fn acl_delete_def_link_np ,
|
|
.Fn acl_delete_fd_np ,
|
|
.Fn acl_delete_file_np ,
|
|
and
|
|
.Fn acl_delete_link_np
|
|
each allow the deletion of an ACL from a file.
|
|
The
|
|
.Fn acl_delete_def_file
|
|
function
|
|
is a POSIX.1e call that deletes the default ACL from a file (normally a
|
|
directory) by name; the remainder of the calls are non-portable extensions
|
|
that permit the deletion of arbitrary ACL types from a file/directory
|
|
either by path name or file descriptor.
|
|
The
|
|
.Fn _file
|
|
variations follow a symlink if it occurs in the last segment of the
|
|
path name; the
|
|
.Fn _link
|
|
variations operate on the symlink itself.
|
|
.Sh IMPLEMENTATION NOTES
|
|
.Fx Ns 's
|
|
support for POSIX.1e interfaces and features is still under
|
|
development at this time.
