Ah, I didn't know Regedit was not giving the true value. That complicates matters even more. It seems I'll have to do some experiments. -- Dave Pickles

I don't see how you can get the right semantics this way, but maybe I missed something. How will you be able to wake a single thread for auto-reset events, but all of them for manual events? How are you going to implement PulseEvent? How can you do WaitForMultipleObjects for an auto-reset event without a race? -- Alexandre Julliard julliard(a)winehq.com

event flags using pipes
by Mike McCormack April 1, 2001

April 1, 2001

Hi, i've written an implementation of windows event flags using pipes. (The modifications are confined to server/event.c for the moment.) Why? By changing the client side implementation of SetEvent and ResetEvent the use file descriptors and implementing a client side unix fd/handle cache, it should be possible to eliminate server calls for these operations and improve the performance of wineserver. Anyway, any comments are welcome.
