No you can't pass a parameter except a name.
What is the idea behind that you need to pass a parameter to a synch object?

Do you need maybe to know who set the event? If yes, then this should do it: Waiting for Multiple Objects - Windows applications | Microsoft Docs[^]

I have some threads which receives multiple messages and i want to know the type of the message in the signaled thread.
By the way, can multiple threads wait for a single event? if so, if the event is signaled then all the waiting threads signaled?
