The return values from res_search() are defined in
/usr/include/netdb.h as follows:
/* Possible values left in `h_errno'. */
#define NETDB_INTERNAL -1 /* See errno. */
#define NETDB_SUCCESS 0 /* No problem. */
#define HOST_NOT_FOUND 1 /* Authoritative Answer Host not found. */
#define TRY_AGAIN 2 /* Non-Authoritative Host not found,
or SERVERFAIL. */
#define NO_RECOVERY 3 /* Non recoverable errors, FORMERR, REFUSED,
NOTIMP. */
#define NO_DATA 4 /* Valid name, no data record of requested
type. */
#define NO_ADDRESS NO_DATA /* No address, look for MX record. */
