术语 | createtimerqueue |
释义 | CreateTimerQueue 语法: C++ HANDLE WINAPI CreateTimerQueue(void); CreateTimerQueue功能 创建一个定时器队列。定时器队列定时器是轻量级的对象,使您能够指定一个回调函数将在指定的时间要求。 参数 这个函数没有参数。 返回值 如果函数成功,返回值是一个句柄计时器队列。这种处理只能在函数中使用要求的句柄计时器队列。 如果函数失败,返回值为NULL。为了获得更多错误信息,调用GetLastError。 备注 要添加一个定时器队列,调用CreateTimerQueueTimer功能。为了从队列中删除一个定时器,调用DeleteTimerQueueTimer功能。 When you are finished with the queue of timers, call the DeleteTimerQueueEx function to delete the timer queue.在队列中的所有未结定时器被取消和删除。 要编译的应用程序使用此功能,定义_WIN32_WINNT为0x0500或更高版本。有关详细信息,请参阅使用Windows头。 实例 举一个例子,它使用CreateTimerQueue,请参阅使用定时器队列。 要求: 最低支持:client-Windows 2000专业版 最低支持server-Windows 2000服务器 HeaderWinbase.h(头文件:winuser.h) LibraryKernel32.lib DLLKernel32.dll 参见 CreateTimerQueueTimer DeleteTimerQueueEx DeleteTimerQueueTimer 同步功能 线程池 定时器队列 如果有任何问题和意见,请发送给微软(wsddocfb@microsoft.com) 生成日期:2009年8月27日 ==英文原文==CreateTimerQueue Function Creates a queue for timers. Timer-queue timers are lightweight objects that enable you to specify a callback function to be called at a specified time. Syntax C++ HANDLE WINAPI CreateTimerQueue(void); Parameters This function has no parameters. Return Value If the function succeeds, the return value is a handle to the timer queue. This handle can be used only in functions that require a handle to a timer queue. If the function fails, the return value is NULL. To get extended error information, call GetLastError . Remarks To add a timer to the queue, call the CreateTimerQueueTimer function. To remove a timer from the queue, call the DeleteTimerQueueTimer function. When you are finished with the queue of timers, call the DeleteTimerQueueEx function to delete the timer queue. Any pending timers in the queue are canceled and deleted. To compile an application that uses this function, define _WIN32_WINNT as 0x0500 or later. For more information, see Using the Windows Headers .
