SYNOPSIS

       #include <ares.h>

       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

       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;
           };
