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(3).

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:

15 ARES_SUCCESS The response was successfully parsed.

15 ARES_EBADRESP The response was malformatted.

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

15 ARES_ENOMEM Memory was exhausted.
