and and sets
errno
to the corresponding value:

-

does not point to a valid ACL.
The ACL has more entries than the file referred to by
fd
can obtain.
- Bq Er ENOSPC
-
The directory or file system that would contain the new ACL cannot be extended or the file system is out of file allocation resources.
- Bq Er ENOTSUP
-
The file identified by

cannot be associated with the ACL because the file system on which the file
is located does not support this.
- Bq Er EPERM
