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.
