Standard C Library (libc, -lc)

int
acl_set_qualifier
(acl_entry_t
entry_d, const void
*tag_qualifier_p);
The
acl_set_qualifier
()
function is a POSIX.1e call that sets the qualifier of the tag for the ACL
entry entry_d to the value referred to by
tag_qualifier_p.
The tag type of the ACL entry, as previously set with
acl_set_tag_type(3), must be
either ACL_EXTENDED_ALLOW
or
ACL_EXTENDED_DENY
, and
tag_qualifier_p should be a pointer to a global unique
identifier (of type guid_t).
The acl_set_qualifier
() function returns
the value 0 if successful; otherwise the value -1 is returned
and the global variable errno is set to indicate the
error.
The acl_set_qualifier
() function fails
if:
EINVAL
]ACL_EXTENDED_ALLOW
or
ACL_EXTENDED_DENY
. The value pointed to by
tag_qualifier_p is not valid.ENOMEM

POSIX.1e is described in IEEE POSIX.1e draft 17.
