Constructs a named or unnamed event object.

Список параметров

name: The name of the event if this is a named event object.

Замечание:
If the name already exists, it must be able to be opened by the current user that the process is running as or an exception will be thrown with a meaningless error message.
manual: Specifies whether or not the event object must be reset manually.

Замечание:
Manual reset event objects allow all waiting processes through until the object is reset.
prefire: Specifies whether or not to prefire (signal) the event object.

Замечание:
Only has impact if the calling process/thread is the first to create the object.
