The
acl_size ();
function return the size, in bytes, of the buffer required to hold the exportable, contiguous, persistent form of the ACL pointed to by the argument

continue to refer to the ACL. The order of ACL entries within
acl
remains unchanged.
RETURN VALUE
On success, the
acl_size ();
function returns the size in bytes of the contiguous, persistent form of
the ACL. On error, a value of
(ssize_t)-1
is returned and
errno
is set appropriately.
ERRORS

acl_size ();
function returns a value of

and sets
