Libevent doesn't handle HANDLEs. To handle HANDLE handling, we'd need switch to a WaitForMultipleObjects/RegisterWaitForSingleObject backend, which would have some drawbacks for implementing the rest of libevent, and which would require user opt-in because of changes to EV_WRITE semantics. Or alternatively, we might add such a backend but only use it for HANDLES. As a workaround for now, you can have one thread doing WaitForMultipleObjects (or use RegisterWaitForSingleObject if that's more appropriate), and have a callback that responds to the HANDLE becoming active by calling evnet_active on an event, so that the event's callback runs in the main thread. -- Nick *********************************************************************** To unsubscribe, send an e-mail to majord...@freehaven.net with unsubscribe libevent-users in the body.
