Hi I have tried to find a way to have a thread take over the event waiting from another thread. This should be done without context switching. A more precise description: 1. Thread A are waiting in poll or epoll. 2. Thread B decides to take over the waiting. This means stopping thread A from responding to new events and go into a (e)poll for the same events. 3. After handling some events thread B decides to let thread A take over again. This should be done without context switching. At least in step 3. The only way I can think of is using two epoll fd's (e0 and e1). e0 should just contain e1 and e1 should contain the actual events: Thread A: epoll_wait(e0) epoll_wait(e1) /*handle events*/ Thread B (takeover): epoll_ctl(e0, remove e1) epoll_wait(e1) /*handle events*/ . . epoll_ctl(e0, add e1) I have left out the synchronization. Is there a better way to do this. Perhaps one that also work with plain poll().
