当在Windows 10中的Visual Studio中为64位编译时,Wow64DisableWow64FsRedirection()函数无法正常工作
问题描述:
我面临Wow64DisableWow64FsRedirection()
的问题。当在Windows 10中的Visual Studio中为64位编译时,Wow64DisableWow64FsRedirection()函数无法正常工作
当我编译在Visual Studio 2010在64位平台上,它不是在窗口10个,这与错误1.
返回但是,当我编译为32位平台相反,在窗口10
typedef BOOL(__stdcall *tFSRED)(HMODULE);
HMODULE hKernel = LoadLibrary(_T("Kernel32.dll")); // Get Kernel module handle
if (hKernel == NULL)
{
return 2;
}
tFSRED pFunc;
pFunc = (tFSRED) GetProcAddress(hKernel, "Wow64DisableWow64FsRedirection");
ret = pFunc(&oldValue); // Turn the file the file system redirector off
if (ret == FALSE)
{
_tprintf(_T("\nFile System Redirection could not be turned off. Reason: %d"), GetLastError());
return 4;
}
// ret is always TRUE when compile through 32-bit platform
// but ret return FALSE when compile through 64-bit platform
函数工作在Visual Studio中,如果我编译为64位平台,那么如果我在depends.exe
打开生成EXE编译后,它显示64在EXE的前面。
选择32位平台后,生成的EXE是32位。这个EXE适用于我的情况,但我希望我的EXE是64位的,所以我选择了64位平台,并且我得到了一个64位的EXE,但它并不像我上面所解释的那样工作。
答
WOW64仿真仅适用于在64位系统上运行的32位可执行文件。 64位EXE 不应该尝试使用WOW64功能(除IsWow64Process()
之外),因为EXE不会在WOW64内部运行以开始。这就是为什么你在64位EXE中得到错误代码1(ERROR_INVALID_FUNCTION
)的原因。
所以,要么:
-
ifdef的代码跳过64位编译WOW64功能:
#ifndef _WIN64 typedef BOOL (WINAPI *tFSDisable)(PVOID*); typedef BOOL (WINAPI *tFSRevert(PVOID); HMODULE hKernel = GetModuleHandle(_T("Kernel32")); tFSDisable pDisableFunc = (tFSDisable) GetProcAddress(hKernel, "Wow64DisableWow64FsRedirection"); tFSRevert pRevertFunc = (tFSRevert) GetProcAddress(hKernel, "Wow64RevertWow64FsRedirection"); PVOID oldValue; if ((pDisableFunc) && (pRevertFunc)) { if (!pDisableFunc(&oldValue)) // Turn off the file system redirector { _tprintf(_T("\nFile System Redirection could not be turned off. Reason: %d"), GetLastError()); return 4; } } #endif // do file system operations as needed... #ifndef _WIN64 if ((pDisableFunc) && (pRevertFunc)) { if (!pRevertFunc(oldValue)) // Restore the file system redirector { _tprintf(_T("\nFile System Redirection could not be restored. Reason: %d"), GetLastError()); return 5; } } #endif

省略IFDEF并调用WOW64功能只有
IsWow64Process()
报告目前的过程实际上是在WOW64里面运行的:typedef BOOL (WINAPI tW64P)(HANDLE, PBOOL); typedef BOOL (WINAPI *tFSDisable)(PVOID*); typedef BOOL (WINAPI *tFSRevert(PVOID); HMODULE hKernel = GetModuleHandle(_T("Kernel32")); tW64P pIsWow64Func = (tW64P) GetProcAddress(hKernel, "IsWow64Process"); tFSDisable pDisableFunc = NULL; tFSRevert pRevertFunc = NULL; BOOL bIsWow64 = FALSE; if (pIsWow64Func) { pIsWow64Func(GetCurrentProcess(), &bIsWow64); if (bIsWow64) { pDisableFunc = (tFSDisable) GetProcAddress(hKernel, "Wow64DisableWow64FsRedirection"); pRevertFunc = (tFSRevert) GetProcAddress(hKernel, "Wow64RevertWow64FsRedirection"); } } PVOID oldValue; if ((pDisableFunc) && (pRevertFunc)) { if (!pDisableFunc(&oldValue)) // Turn off the file system redirector { _tprintf(_T("\nFile System Redirection could not be turned off. Reason: %d"), GetLastError()); return 4; } } // do file system operations as needed... if ((pDisableFunc) && (pRevertFunc)) { if (!pRevertFunc(oldValue)) // Restore the file system redirector { _tprintf(_T("\nFile System Redirection could not be restored. Reason: %d"), GetLastError()); return 5; } }
将代码包含在问题主体中,以便您可以将代码格式正确地编码为代码。 – zett42
