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 allo-

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;
};
RETURN VALUES
ares_parse_mx_reply can return any of the following values:

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