23.线程间的等待

创建定时器

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

设置定时器时间

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

等待

1 if (WaitForSingleObject(timer, INFINITE) == WAIT_OBJECT_0)
2         {
3             printf("等待成功");
4         }
5         else
6         {
7             printf("等待失败");
8         }
