I have the this bit of code in netdb.h

/*
* Error return codes from gethostbyname() and gethostbyaddr() (left in
* extern int 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-Authoritive 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 */

and this in resolv.h

/*
* This used to be defined in res_query.c, now it's in herror.c.  It was
* never extern'd by any *.h file before it was placed here.  herror.c is
* part of libresolv.a even though it might make more sense in libnetdb.a
* or even libnet.a.
*/

extern int h_errno;
