yp_order — Checks the freshness of a map


int yp_order(domain, map);
string domain: NIS domain name
string map: NIS map name (or nickname)

yp_order() fetches a map's ID number. The ID number (also called the order number) is updated whenever the map is updated and can be used to ensure that a client is using the most recent map.

Example 1446. Ensure that the passwd map is up-to-date

$domain = yp_get_default_domain ();
$map    = 'passwd';

$ID = yp_order ($domain, $map)
   or die ("Could not fetch the ID for map '$map' under domain '$domain'");
