23.线程间的等待

• 创建定时器

  HANDLE timer = CreateWaitableTimer(NULL, TRUE, NULL);

• 设置定时器时间

  　　//设置时间
          LARGE_INTEGER time;
          time.QuadPart = -20000000;//以微秒为单位

• 等待

  if (WaitForSingleObject(timer, INFINITE) == WAIT_OBJECT_0)
          {
              printf("等待成功");
          }
          else
          {
              printf("等待失败");
          }

        //设置定时器等待2
        SetWaitableTimer(timer, &time, 0, NULL, 0, NULL);//设置定时器等待2两秒
