Blocks until one of the desired notifications has been received. Use function to get notifications about any combination of these events: system, sponsor, or dependent events.

The call returns Boolean status and, on success, the lpEventInfo buffer is filled with information about the event notification. For a description of possible event types, see the EVENTINFO structure.

BOOLEAN RtNotifyEvent(
    DWORD dwEventFlags,
    DWORD dwMilliseconds,
    LPEVENTINFO lpEventInfo
);
