术语 createthreadpoolwork
释义 CreateThreadpoolWork
语法:
C++
PTP_WORK WINAPI CreateThreadpoolWork(
__in PTP_WORK_CALLBACK pfnwk,
__inout_opt PVOID pv,
__in_opt PTP_CALLBACK_ENVIRON pcbe
);
CreateThreadpoolWork功能
创建一个新的工作对象。
参数
pfnwk [in]
回调函数。一名工人线程调用此回调每次调用SubmitThreadpoolWork后的工作对象。详情见WorkCallback。
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_WORK结构,它定义的工作对象。
如果函数失败,返回NULL。要检索扩展的错误信息,调用GetLastError。
备注
要编译的应用程序使用此函数,定义为0x0600或更高_WIN32_WINNT。

==英文原文==CreateThreadpoolWork Function
Creates a new work object.
Syntax
C++
PTP_WORK WINAPI CreateThreadpoolWork(
__in PTP_WORK_CALLBACK pfnwk,
__inout_opt PVOID pv,
__in_opt PTP_CALLBACK_ENVIRON pcbe
);
Parameters
pfnwk [in]
The callback function. A worker thread calls this callback each time you call SubmitThreadpoolWork to post the work object. For details, see WorkCallback .
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_WORK structure that defines the work object.
If the function fails, it returns NULL. To retrieve extended error information, call GetLastError .
Remarks
To compile an application that uses this function, define _WIN32_WINNT as 0x0600 or higher.
Examples
For an example, see Using the Thread Pool Functions .
Requirements
Minimum supported clientWindows Vista
Minimum supported serverWindows Server 2008
