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

       #include <ares.h>

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

       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;

       ares_parse_mx_reply can return any of the following values:

       ARES_SUCCESS   The response was successfully parsed.

       ARES_EBADRESP  The response was malformatted.

       ARES_ENODATA   The response did not contain an answer to the query.

       ARES_ENOMEM    Memory was exhausted.

       This function was first introduced in c-ares version 1.7.2.
