多线程编程线程同步，Events同步

Events 线程同步不太会用，能不能给讲个示例？

官网有更加详细的解释和用法，这个是官网例子

1. // The following demonstrates trivial usage of the CEvent class.
   
2. // A CEvent object is created and passed as a parameter to another
   
3. // thread.  The other thread will wait for the event to be signaled
   
4. // and then exit
   
5. 
   
6. UINT __cdecl MyThreadProc(LPVOID lpParameter)
   
7. {
   
8.    CEvent *pEvent = (CEvent *)(lpParameter);
   
9.    VERIFY(pEvent != NULL);
   
10. 
    
11.    // Wait for the event to be signaled
    
12.    ::WaitForSingleObject(pEvent->m_hObject, INFINITE);
    
13. 
    
14.    // Terminate the thread
    
15.    ::AfxEndThread(0, FALSE);
    
16.    return 0L;
    
17. }
    
18. 
    
19. void CEvent_Test()
    
20. {
    
21.    // Create the CEvent object that will be passed to the thread routine
    
22.    CEvent *pEvent = new CEvent(FALSE, FALSE);
    
23. 
    
24.    // Create a thread that will wait on the event
    
25.    CWinThread *pThread;
    
26.    pThread = ::AfxBeginThread(&MyThreadProc, pEvent, 0, 0, CREATE_SUSPENDED, NULL);
    
27.    pThread->m_bAutoDelete = FALSE;
    
28.    pThread->ResumeThread();
    
29. 
    
30.    // Signal the thread to do the next work item
    
31.    pEvent->SetEvent();
    
32. 
    
33.    // Wait for the thread to consume the event and return
    
34.    ::WaitForSingleObject(pThread->m_hThread, INFINITE);
    
35.    delete pThread;
    
36.    delete pEvent;
    
37. }
