Enumeration Type Documentation

anonymous enum

Enumerator
RESOLV_STATUS_CACHED	Hostname is fresh and usable. This response is cached and will eventually expire to RESOLV_STATUS_EXPIRED.
RESOLV_STATUS_UNCACHED	Hostname was not found in the cache. Use resolv_query() to look it up.
RESOLV_STATUS_EXPIRED	Hostname was found, but it's status has expired. The address returned should not be used. Use resolv_query() to freshen it up.
RESOLV_STATUS_NOT_FOUND	The server has returned a not-found response for this domain name. This response is cached for the period described in the server. You may issue a new query at any time using resolv_query(), but you will generally want to wait until this domain's status becomes RESOLV_STATUS_EXPIRED.
RESOLV_STATUS_RESOLVING	This hostname is in the process of being resolved. Try again soon.
RESOLV_STATUS_ERROR	Some sort of server error was encountered while trying to look up this record. This response is cached and will eventually expire to RESOLV_STATUS_EXPIRED.
