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;
           };
