It is a fact, and 'built-in' feature of UDP, that "If a datagram arrives, it will be uncorrupted" - that statement is not a requirement (to add/support) for the project. I strongly suggest that you read from a textbook or the Beej tutorial to get a background understanding of UDP. There's even an online Linux manual entry for it: "This is an implementation of the User Datagram Protocol described in RFC 768. It implements a connectionless, unre- liable datagram packet service. Packets may be reordered or duplicated before they arrive. UDP generates and checks checksums to catch transmission errors."
