NAME

       ares_parse_naptr_reply - Parse a reply to a DNS query of type NAPTR

SYNOPSIS

       #include <ares.h>

       int ares_parse_naptr_reply(const unsigned char* abuf, int alen,
                                  struct ares_naptr_reply** naptr_out);

DESCRIPTION

       The  ares_parse_naptr_reply  function  parses the response to a query of type NAPTR into a linked list of
       struct ares_naptr_reply The parameters abuf and alen give the contents of the response.   The  result  is
       stored  in  allocated memory and a pointer to it stored into the variable pointed to by naptr_out.  It is
       the caller's responsibility to free the resulting naptr_out structure when it is no longer  needed  using
       the function ares_free_data(3).

       The structure ares_naptr_reply contains the following fields:

           struct ares_naptr_reply {
               struct ares_naptr_reply *next;
               unsigned char *flags;
               unsigned char *service;
               unsigned char *regexp;
               char *replacement;
               unsigned short order;
               unsigned short preference;
           };

       ares_parse_naptr_reply can return any of the following values:

       ARES_SUCCESS   The response was successfully parsed.
