acl
continue to refer to the same entries. Any existing ACL pointers that refer
to the ACL referred to by

acl
remains unchanged.

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

Fn acl_size
function returns a value of
