I see,so you mean that the child thread can't poll. What if he combines polling the event with non blocking IO ?

    That is certainly an option, but once you move to non-blocking IO and polling, a simple shared variable transitioning from false to true is far simpler than a kernel-based event mechanism.

    The problem with non-blocking IO is that you then have manually replicate all the functionality of readline, eof etc. in user code which is a retrograde step. Especially when there are simpler ways.
