DESCRIPTION

15       The ares_parse_mx_reply function parses the response to a query of type
16       MX into a linked list of struct ares_mx_reply The parameters  abuf  and
17       alen  give the contents of the response.  The result is stored in allo‐
18       cated memory and a pointer to it stored into the variable pointed to by
19       mx_out.  It is the caller's responsibility to free the resulting mx_out
20       structure when it is no longer needed using the function ares_free_data
21
22       The structure ares_mx_reply contains the following fields:
23
24           struct ares_mx_reply {
25               struct ares_mx_reply *next;
26               char *host;
27               unsigned short priority;
28           };
