Good question.

Here's excerpts from UnixWare's /usr/include/netdb.h:

/** Flag values for getaddrinfo()*/
#define AI_PASSIVE      0x01    /* socket address is intended for bind() */
#define AI_CANONNAME    0x02    /* request for canonical name */
/** Error values for getaddrinfo()*/
#define EAI_BADFLAGS    1       /* invalid value for ai_flags */
#define EAI_NONAME      2       /* neither name nor service provided/found 
*/
#define EAI_AGAIN       3       /* temporary failure in name resolution */
#define EAI_FAIL        4       /* non-recoverable failure in name resoln */
#define EAI_NODATA      5       /* no address associated with name */
#define EAI_FAMILY      6       /* ai_family not supported */
#define EAI_SOCKTYPE    7       /* ai_socktype not supported */
#define EAI_SERVICE     8       /* service not supported for ai_socktype */
#define EAI_ADDRFAMILY  9       /* address family for name not supported */
#define EAI_MEMORY      10      /* memory allocation failure */
#define EAI_SYSTEM      11      /* system error */
/** Structure used by getaddrinfo()*/
struct addrinfo {       int             ai_flags;       /* input flags */       int             ai_family;      /*
protofamilyfor socket */       int             ai_socktype;    /* socket type */       int             ai_protocol;
/*protocol for socket */       int             ai_addrlen;     /* length of socket address */       struct sockaddr
*ai_addr;      /* socket address */       char            *ai_canonname;  /* canonical name for service locn 
 
*/       struct addrinfo *ai_next;       /* pointer to next in list */
};


a copy of the manpage is at:

I'm at a loss from here....
