Hi All,
I know that getaddrinfo() return the multiple IP addresses (if present) for a hostname. But, I want to know how to get the TTL value for this list from DNS. I want to get this TTL value and cache this IP address list for that much time and then again go for DNS resolution if TTL expires.

Hi there,
I'm trying to do an MX type lookup using getaddrinfo(), but I can't work out how to change the lookup type to MX from the standard A - can anybody tell me how to do this?
Thanks very much
