Blocking vs. nonblocking UDP socket for single host?

If you have a dedicated thread for handling the socket then asynchronous I/O select etc are useless. What you want is simply recvfrom(2) and handle the data as quickly as possible.

With only a few peers, (and 'one' is surely in this set:), a thread with a blocking socket should be fine. The code is easier to write since state can be maintained in the dedicated thread - no need for the state-machines that are usually required with a non-blocking system.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
