I'm planning on using c-ares for making mx record searches and
possibly txt record searches. This is what I've tried, error checking
and obvious stuff removed for clarity:
int main() {
unsigned char *buf;
int buflen;
struct ares_mx_reply *out;
ares_library_init(ARES_LIB_INIT_ALL);
ares_init(&channel);
/* 1 = INTERNET, 15 = MX */
ares_create_query(host, 1, 15, 0x1234, 1, &buf, &buflen, 0);
wait_ares(channel);
ares_parse_mx_reply(buf, buflen, &out);
...
}
this is where it errors out due to an empty response. I'm guessing
I'm using the library wrong, but not sure.
Thanks,

Fixed my problem by using ares_query() instead. I'm guessing the
ares_create_query() doesn't actually send the query perhaps its a lower
level function used within the library?
Thanks,
Edgar
