public SyncEvent::__construct ([ string $name [, bool $manual = false [, bool $prefire = false ]]] )

Constructs a named or unnamed event object.

Note:

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.
