Re: Waiting for event

Tech-Archive recommends: Speed Up your PC by fixing your registry

The clients perform a clean-up task that may take several seconds. The
clients are using WaitForMultipleObject on the event (they are also waiting
for other things).

I've read and re-read the MSDN docs and it seem to imply that:

1. Auto-resetting = Will ONLY release one waiting thread (this is
intentional)

2. Manual resetting = Will release all waiting threads, but this isn't made
explicitly clear.

What would be the best technique to ensure no waiting thread misses the
event?

It depend on what the client do when the event is signalled.

I've got a situation where multiple client processes are waiting for an
event that is signalled by a server process. The event is created by the
server process which then launches the clients. The clients then wait on
the event. The event can be signalled multiple times.

I originally wanted to make the event auto-resetting, but when I read up
on it in MSDN it said that auto-resetting events are reset as soon as the
first waiting thread is signalled.

What is the correct way to handle this situation please? I know I cannot
use a self-resetting event, but what should I do after signalling the
event to ensure that all the clients have synchronized on it - will ALL
clients always synchronize even if the event is rapidly reset?
