SYNOPSIS

9       #include <ares.h>
10
11       int ares_parse_mx_reply(const unsigned char* abuf, int alen,
12                               struct ares_mx_reply** mx_out);

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
21       ares_free_data(3).
22
23       The structure ares_mx_reply contains the following fields:
24
25           struct ares_mx_reply {
26               struct ares_mx_reply *next;
27               char *host;
28               unsigned short priority;
29           };
