Kill a blocking thread in C's pthread gracefully?

You problem is actually "how to interrupt blocking system call from other thread".

The answer to this is to not do anything that will block without a timeout. For IO, you shouldn't call read() until you know the call will not block. For example, use poll() or select() on the path first in order to determine the status.

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.
