ARES_PARSE_NAPTR_REPLY(3)                     FreeBSD Library Functions Manual

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

       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;
           };
