So, assuming that you also do an event_add(ev1, NULL), this code will ordinarily stay inside event_base_dispatch until there are no more pending events (that is, until somebody calls event_del(ev1), or until you call event_base_loopexit, or until you call event_base_loopbreak(). The question to answer may be, which of these cases was making it exit event_base_dispatch() before? If that doesn't shed light on the problem, I'd try using a debugger to see whether your program is getting stuck in event_base_dispatch, and if so, which of the conditions that should be making event_base_dispatch exit isn't happening. *********************************************************************** To unsubscribe, send an e-mail to majord...@freehaven.net with unsubscribe libevent-users in the body.
