parseUdpHeader :: Get (UdpHeader, Int) Source
Parse out a UdpHeader, and the size of the payload.
renderUdpHeader :: UdpHeader -> Int -> Put Source
Render a UdpHeader.
renderUdpPacket :: UdpHeader -> ByteString -> MkPseudoHeader -> IO ByteString Source
Given a way to make the pseudo header, render the UDP packet.
validateUdpChecksum :: IP4 -> IP4 -> ByteString -> Bool Source
Recreate the UDP checksum, given a rendered packet, and the source and destination.
