TYPE

 This is a portable idealized form that need not match the
underlying platform. This is sorted by size and then by name. 
  struct_hostent = RECORD
    h_addr_list:  char_star_star;
    h_aliases:    char_star_star;
    h_name:       char_star;
    h_addrtype:   int; (* underlying implementation varies here *)
    h_length:     int; (* underlying implementation varies here *)
  END;
  struct_hostent_star = UNTRACED REF struct_hostent;

CONST

<*EXTERNAL "Unetdb__TRY_AGAIN"*>   VAR TRY_AGAIN:   int;
<*EXTERNAL "Unetdb__NO_RECOVERY"*> VAR NO_RECOVERY: int;
<*EXTERNAL "Unetdb__NO_ADDRESS"*>  VAR NO_ADDRESS:  int;

 These are thin C wrappers that do not quite match the underlying
   function, but are very close.
success:
    native struct is copied into provided struct, and pointer to provided
    struct returned
failure:
    null returned


Despite the result buffer provided, the functions are no more thread safe
than their underlying implementation.
