so, I should use an extra ev_async to call ev_feed_event for that ev_timer? This ev_async in the same thread, and call ev_feed_event in its callback.

Not without locking the event loop, e.g. with a mutex (you could use the acquire/release callbacks and an ev_async watcher to lock/unlock and wake up the loop). > Is it safe? Without proper locking, no, it will most likely corrupt libev's internal data structures and not even work. -- The choice of a Deliantra, the free code+content MORPG -----==- _GNU_ http://www.deliantra.net ----==-- _ generation ---==---(_)__ __ ____ __ Marc Lehmann --==---/ / _ \/ // /\ \/ / [email protected] -=====/_/_//_/\_,_/ /_/\_\
