* Important note regarding the BIND-9 API on Mac OS
* -------------------------------------------------
*
* Mac OS supports a DNS query routing API (see <dns.h>) which is used by
* most system services to access DNS. The BIND-9 APIs described here are
* a lower-level that does not do query routing or search amongst multiple
* resolver clients. The results of DNS queries from this API may differ
* significantly from the results of queries sent to the <dns.h> API. We
* strongly encourage developers to use higher-level APIs where possible.
