| 释义 | GetThreadSelectorEntry 语法： C++ BOOL WINAPI GetThreadSelectorEntry( __in HANDLE hThread, __in DWORD dwSelector, __out LPLDT_ENTRY lpSelectorEntry ); GetThreadSelectorEntry功能 检索一个描述符指定的选择和线程表项。 参数 hThread [in] 阿线程句柄包含指定选择。句柄必须THREAD_QUERY_INFORMATION访问。有关更多信息，请参见线程安全和访问权限。 dwSelector [in] 全球或地区选择器的值来查找在线程的描述符表。 lpSelectorEntry [out] 对一个LDT_ENTRY结构，也能收到描述符表项的副本指针指定的选择，如果有一个在指定线程的描述符表项。这些信息可用于转换技术领域的相对地址为线性虚拟地址。 返回值 如果函数成功，返回值为非零。在这种情况下，所指出的结构参数的lpSelectorEntry收到指定的描述符表项的副本。 如果函数失败，返回值是零。为了获得更多错误信息，调用GetLastError。 备注 GetThreadSelectorEntry只是功能在基于x86的系统。对于系统是不是基于x86，函数返回FALSE。 调试器使用此函数将部分相对虚拟地址到线性地址。在ReadProcessMemory的使用功能和WriteProcessMemory的线性虚拟地址。 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 调试功能 LDT_ENTRY ReadProcessMemory的 WriteProcessMemory的 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7月30日 ＝＝英文原文＝＝GetThreadSelectorEntry Function Retrieves a descriptor table entry for the specified selector and thread. Syntax C++ BOOL WINAPI GetThreadSelectorEntry( __in HANDLE hThread, __in DWORD dwSelector, __out LPLDT_ENTRY lpSelectorEntry ); Parameters hThread [in] A handle to the thread containing the specified selector. The handle must have THREAD_QUERY_INFORMATION access. For more information, see Thread Security and Access Rights . dwSelector [in] The global or local selector value to look up in the thread's descriptor tables. lpSelectorEntry [out] A pointer to an LDT_ENTRY structure that receives a copy of the descriptor table entry if the specified selector has an entry in the specified thread's descriptor table. This information can be used to convert a segment-relative address to a linear virtual address. Return Value If the function succeeds, the return value is nonzero. In that case, the structure pointed to by the lpSelectorEntry parameter receives a copy of the specified descriptor table entry. If the function fails, the return value is zero. To get extended error information, call GetLastError . Remarks GetThreadSelectorEntry is only functional on x86-based systems. For systems that are not x86-based, the function returns FALSE. Debuggers use this function to convert segment-relative addresses to linear virtual addresses. The ReadProcessMemory and WriteProcessMemory functions use linear virtual addresses.
