From UDP: the User Datagram Protocol

Although UDP provides error checking, it does not do anything to recover from an error. Some implementations of UDP simply discard the damaged segment; others pass the damaged segment to the application with a warning.
So getting the checksum is OS and IP-stack implementation-dependent. BTW: How are you dealing with missing packets? (you are tracking sequence numbers, yes?)
