You can't be sure in any case that a udp message i.e.
received is not. Because this protocol is designed in a way
that it is used generally where packet loss is regular.It is
unreliable opposite of TCP protocol. UDP does not require
handshaking . It is generally used in the situation where
packet/data delay should not occur because of packet drop.
So you can't give guarantee of receiving your packet. Only
way is check-sum of your file.
