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.
variations follow a symlink if it occurs in the last segment of the
path name; the
variations operate on the symlink itself.

support for POSIX.1e interfaces and features is still under
development at this time.
If any of the following conditions occur, these functions shall return -1
to the corresponding value:
Bq Er EACCES
Search permission is denied for a component of the path prefix, or the
object exists and the process does not have appropriate access rights.
Bq Er EBADF
argument is not a valid file descriptor.
Bq Er EINVAL
The ACL type passed is invalid for this file object.
Bq Er ENAMETOOLONG
A component of a pathname exceeded 255 characters, or an
entire path name exceeded 1023 characters.
Bq Er ENOENT
The named object does not exist, or the
argument points to an empty string.
Bq Er ENOMEM
Insufficient memory available to fulfill request.
Bq Er ENOTDIR
A component of the path prefix is not a directory.
must be a directory, and is not.
Bq Er EOPNOTSUPP
The file system does not support ACL deletion.
Bq Er EPERM
The process does not have appropriate privilege to perform the operation
to delete an ACL.
POSIX.1e is described in IEEE POSIX.1e draft 17.
of the draft continues on the cross-platform POSIX.1e implementation

POSIX.1e support was introduced in
Fx 4.0 ,
and development continues.
