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


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.
