Call recv() on the same blocking socket from two threads?

One thread will get it, and there's no way to tell which.

Socket implementations should be thread-safe, so exactly one thread should get the data when it becomes available. The other call should just block.

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.
