| 术语 | timerapcproc |
| 释义 | TimerAPCProc 语法： C++ VOID CALLBACK TimerAPCProc( __in_opt LPVOID lpArgToCompletionRoutine, __in DWORD dwTimerLowValue, __in DWORD dwTimerHighValue ); TimerAPCProc回调函数 一个应用程序定义的定时器完成例程。指定这个地址时调用SetWaitableTimer功能。在PTIMERAPCROUTINE类型定义一个指向这个回调函数。 TimerAPCProc是一个应用程序的占位符定义函数的名称。 参数 lpArgToCompletionRoutine [中，可选] 传递给函数使用该SetWaitableTimer功能lpArgToCompletionRoutine参数的值。 dwTimerLowValue [in] 低的星期日秩序的一部分的时间计时器是该信号。此值对应于FILETIME结构dwLowDateTime成员。如需有关星期日信息化时，看到系统时间。 dwTimerHighValue [in] 在高星期日秩序部分，基于时间的计时器的信号。此值对应于FILETIME结构dwHighDateTime成员。 返回值 这个函数没有返回值。 备注 完成例程执行的线程激活计时器使用SetWaitableTimer。但是，线程必须在一个可报警状态。有关更多信息，请参阅异步过程调用。 实例 有关示例，请参阅使用一个异步过程调用一可等待计时器。 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) 参见 SetWaitableTimer 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＝＝TimerAPCProc Callback Function An application-defined timer completion routine. Specify this address when calling the SetWaitableTimer function. The PTIMERAPCROUTINE type defines a pointer to this callback function. TimerAPCProc is a placeholder for the application-defined function name. Syntax C++ VOID CALLBACK TimerAPCProc( __in_opt LPVOID lpArgToCompletionRoutine, __in DWORD dwTimerLowValue, __in DWORD dwTimerHighValue ); Parameters lpArgToCompletionRoutine [in, optional] The value passed to the function using the lpArgToCompletionRoutine parameter of the SetWaitableTimer function. dwTimerLowValue [in] The low-order portion of the UTC-based time at which the timer was signaled. This value corresponds to the dwLowDateTime member of the FILETIME structure. For more information about UTC-based time, see System Time . dwTimerHighValue [in] The high-order portion of the UTC-based time at which the timer was signaled. This value corresponds to the dwHighDateTime member of the FILETIME structure. Return Value This function does not return a value. Remarks The completion routine is executed by the thread that activates the timer using SetWaitableTimer . However, the thread must be in an alertable state. For more information, see Asynchronous Procedure Calls . Examples For an example, see Using a Waitable Timer with an Asynchronous Procedure Call .
