45 * acl_valid: accepts an ACL, returns 0 on valid ACL, -1 for invalid,
46 * and errno set to EINVAL.
48 * Implemented by calling the acl_check routine in acl_support, which
49 * requires ordering. We call acl_support's _posix1e_acl_sort to make this
50 * true. POSIX.1e allows acl_valid() to reorder the ACL as it sees fit.
52 * This call is deprecated, as it doesn't ask whether the ACL is valid
53 * for a particular target. However, this call is standardized, unlike
54 * the other two forms.
