in reply to Kill and free the memory Never ending threads from main

Approach the problem this way:   the event just means, “you should not be asleep right now.”   (Not “please wake up.”)   The main-loop of the thread is driven by a set of shared flags which tell it what it should do next, one of the choices being “die now.”

while (1) { if (shared.die) { exit; } elsif (shared.do_this) { do_this; } elsif (shared.do_that) { do_that; } ... else { wait_for_event(); } }

The parent thread first sets one of the flags, then strobes the event to be sure that the child is not-asleep to respond to it.

You don’t need to invent these things from scratch.   Look at existing workhorses such as POE.
