c++ - 如何检测我的软件是否在 Windows XP 上运行？

Question

我运行了一些代码来检测 Windows XP，我认为它应该可以工作，但是我应该用什么替换“??”来检测我是否在 Windows XP 上运行？

bool IsWindowsXP()
{
    bool isWindowsXp = false;

    OSVERSIONINFOEX osvi;
    ZeroMemory(&osvi, sizeof(OSVERSIONINFOEX));
    osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX);
    if( GetVersionEx((OSVERSIONINFO*)&osvi) )
    {
        const DWORD MinXpVersion = ??;
        const DWORD MaxXpVersion = ??;
        if ((osvi.dwPlatformId == VER_PLATFORM_WIN32_NT) && 
            (vi.dwMajorVersion >= MinXpVersion) &&
            (vi.dwMajorVersion <= MinXpVersion))
        {
            isWindowsXp = false;
        }
    }

    return isWindowsXp;
}

在 OSVERSIONINFOEX 的文档页面上结构，两个相关字段是这样说的:

For more information, see Remarks.

在备注部分下方有一个方便的表格:

Windows Server 2003       5.2            5              2        GetSystemMetrics(SM_SERVERR2) == 0
Windows XP Prof x64 Ed    5.2            5              2        (OSVERSIONINFOEX.wProductType == VER_NT_WORKSTATION) && (SYSTEM_INFO.wProcessorArchitecture==PROCESSOR_ARCHITECTURE_AMD64)
Windows XP                5.1            5              1        Not applicable
Windows 2000              5              5              0        Not applicable

如表所示，XP 为 5.1。
