SYNOPSIS

       #include <ares.h>

       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;
           };
