|
|
.Fd #include <sys/types.h>

|
.Fd #include <sys/acl.h>

.Sh DESCRIPTION
|
|
The
|
|
.Fn acl_delete_def_file ,
|
|
.Fn acl_delete_file_np ,
|
|
and
|
|
.Fn acl_delete_fd_np
|
|
each allow the deletion of an ACL from a file.
|
|
.Fn acl_delete_def_file
|
|
is a POSIX.1e call that deletes the default ACL from a file (normally a
|
|
directory) by name; the other two calls are non-portable extensions that
|
|
allow deleting of arbitrary ACL types from a file/directory by either path
|
|
name, or by file descriptor.
|
|
.Sh IMPLEMENTATION NOTES
|
|
FreeBSD's support for POSIX.1e interfaces and features is still under
|
|
development at this time.
|
|

.Sh STANDARDS

|
POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion
|
|
of the draft continues on the cross-platform POSIX.1e implementation
|
|
mailing list. To join this list, see the FreeBSD POSIX.1e implementation
|
|
page for more information.
|
|
.Sh HISTORY
|
|
POSIX.1e support was introduced in FreeBSD 4.0, and development continues.

|
.Sh BUGS
|
|
These features are not yet fully implemented. In particular, the shipped
|
|
version of UFS/FFS does not support storage of additional security labels,
|
|
and so is unable to (easily) provide support for most of these features.
