Socket programming, checking entry UDP buffer is empty or not?

I think the problems (unsatisfying behavior you do not describe) come from a different source. Let me just list some ideas and comments c. / what was said before.

Use select() (with a suitable timeout) to check for incoming data prior to calling recv().

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.
