| 释义 | SetThreadContext 语法： C++ BOOL WINAPI SetThreadContext( __in HANDLE hThread, __in const CONTEXT *lpContext ); SetThreadContext功能 设置指定线程上下文。 64位应用程序可以设置一个WOW64的使用Wow64SetThreadContext函数线程上下文。 参数 hThread [in] 句柄到线程的上下文被设置。句柄必须有THREAD_SET_CONTEXT访问权的线程。有关更多信息，请参见线程安全和访问权限。 lpContext [in] 甲到一个上下文结构，包含要在指定的范围内设置的线程指针。在这个结构ContextFlags成员值指定一个线程的上下文哪些部分设置。在上下文结构不能指定有些值是默默设置为正确的值。这包括CPU状态寄存器位指定的特权处理器模式，在调试寄存器全球扶持位，必须由操作系统控制的其他国家。 返回值 如果上下文成立，则返回值为非零。 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 该函数设置线程上下文的上下文结构ContextFlags成员的值为基础。由hThread参数确定的线程通常是进行调试，但也能操作的功能即使在没有线程调试。 不要试图为正在运行的线程上下文，结果难以预料。使用SuspendThread函数之前调用SetThreadContext暂停线程。 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 背景 调试功能 GetThreadContext SuspendThread 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＝＝SetThreadContext Function Sets the context for the specified thread. A 64-bit application can set the context of a WOW64 thread using the Wow64SetThreadContext function. Syntax C++ BOOL WINAPI SetThreadContext( __in HANDLE hThread, __in const CONTEXT *lpContext ); Parameters hThread [in] A handle to the thread whose context is to be set. The handle must have the THREAD_SET_CONTEXT access right to the thread. For more information, see Thread Security and Access Rights . lpContext [in] A pointer to a CONTEXT structure that contains the context to be set in the specified thread. The value of the ContextFlags member of this structure specifies which portions of a thread's context to set. Some values in the CONTEXT structure that cannot be specified are silently set to the correct value. This includes bits in the CPU status register that specify the privileged processor mode, global enabling bits in the debugging register, and other states that must be controlled by the operating system. Return Value If the context was set, the return value is nonzero. If the function fails, the return value is zero. To get extended error information, call GetLastError . Remarks The function sets the thread context based on the value of the ContextFlags member of the context structure. The thread identified by the hThread parameter is typically being debugged, but the function can also operate even when the thread is not being debugged. Do not try to set the context for a running thread; the results are unpredictable. Use the SuspendThread function to suspend the thread before calling SetThreadContext.
