NAME

       ares_parse_mx_reply - Parse a reply to a DNS query of type MX

SYNOPSIS

       #include <ares.h>

       int ares_parse_mx_reply(const unsigned char* abuf, int alen,
       struct ares_mx_reply** mx_out);

DESCRIPTION

       The  ares_parse_mx_reply  function parses the response to a query of type MX into a linked
       list of struct ares_mx_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 mx_out.  It is the caller's responsibility to  free  the  resulting
       mx_out structure when it is no longer needed using the function ares_free_data

       The structure ares_mx_reply contains the following fields:

           struct ares_mx_reply {
               struct ares_mx_reply *next;
               char *host;
               unsigned short priority;
           };
