Would seem to suggest not.

I have three processes communicating via pipes. Process A C

I hope this example can help you:

handle1A = CreateEvent(LPSECURITY_ATTRIBUTES, ManualReset, InitialState, NAME)

handle1B = CreateEvent(LPSECURITY_ATTRIBUTES, ManualReset, InitialState, NAME)

handle2A = CreateEvent(LPSECURITY_ATTRIBUTES, ManualReset, InitialState, NAME+GetCurrentThreadId())

handle2B = CreateEvent(LPSECURITY_ATTRIBUTES, ManualReset, InitialState, NAME+GetCurrentThreadId())

A) if you create a event with the same NAME, every setEvent signaling all waitforsingleobjects

SetEvent(handle1A) // Send signaling to handle1A and handle1B

B) if you create a event whith a unique NAME, the setEvent only sends the signal to referenced handle

SetEvent(handle2) // Send signling only to handle2A. The Id Thread is unique
