释义 | CreateThreadpoolIo 语法: C++ PTP_IO WINAPI CreateThreadpoolIo( __in HANDLE fl, __in PTP_WIN32_IO_CALLBACK pfnio, __inout_opt PVOID pv, __in_opt PTP_CALLBACK_ENVIRON pcbe ); CreateThreadpoolIo功能 创建一个新的I / O完成对象。 参数 fl [in] 该文件句柄绑定到这个I / O完成对象。 pfnio [in] 回调函数的调用,在每一次重叠I / O操作完成的文件。详情见IoCompletionCallback。 光伏[中,指出,可选] 可选应用程序定义的数据传递给回调函数。 pcbe [中,可选] 阿TP_CALLBACK_ENVIRON结构,它定义的环境中执行回调。该InitializeThreadpoolEnvironment函数返回这个结构。 如果该参数为NULL,回调执行在默认的回调环境。有关更多信息,请参阅InitializeThreadpoolEnvironment。 返回值 如果函数成功,它返回一个TP_IO结构,它定义的I / O对象。 如果函数失败,返回NULL。要检索扩展的错误信息,调用GetLastError。 备注 开始接收重叠I / O完成回调,调用StartThreadpoolIo功能。 要编译的应用程序使用此函数,定义为0x0600或更高_WIN32_WINNT。 要求: client最低支持Vista server最低支持 Windows Server 2008 HeaderWinbase.h(头文件:winuser.h) LibraryKernel32.lib DLLKernel32.dll 参见 CancelThreadpoolIo CloseThreadpoolIo StartThreadpoolIo 线程池 WaitForThreadpoolIoCallbacks 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==CreateThreadpoolIo Function Creates a new I/O completion object. Syntax C++ PTP_IO WINAPI CreateThreadpoolIo( __in HANDLE fl, __in PTP_WIN32_IO_CALLBACK pfnio, __inout_opt PVOID pv, __in_opt PTP_CALLBACK_ENVIRON pcbe ); Parameters fl [in] The file handle to bind to this I/O completion object. pfnio [in] The callback function to be called each time an overlapped I/O operation completes on the file. For details, see IoCompletionCallback . pv [in, out, optional] Optional application-defined data to pass to the callback function. pcbe [in, optional] A TP_CALLBACK_ENVIRON structure that defines the environment in which to execute the callback. The InitializeThreadpoolEnvironment function returns this structure. If this parameter is NULL, the callback executes in the default callback environment. For more information, see InitializeThreadpoolEnvironment . Return Value If the function succeeds, it returns a TP_IO structure that defines the I/O object. If the function fails, it returns NULL. To retrieve extended error information, call GetLastError . Remarks To begin receiving overlapped I/O completion callbacks, call the StartThreadpoolIo function. To compile an application that uses this function, define _WIN32_WINNT as 0x0600 or higher.
