获取Windows体系结构（32/64位版本）
我遇到了一个小问题：
我想获取操作系统的体系结构，问题是我的编程语言不支持此类功能。因此我需要从 Windows DLL（如 kernel32.dll）读取此信息
我确实尝试使用函数 GetNativeSystemInfo/GetVersionEx/GetSystemInfo 获取信息。
不幸的是我无法获得架构：/
是否有其他一些函数可以读取任何 Windows dll 中的架构？
（它不需要是 kernel32，它可以是任何 dll，但它必须存在于 win xp+ 中）
作为信息：我使用 Gupta (SQLWindows/Team devoloper)
Edit1:
typedef struct _SYSTEM_INFO {
union {
DWORD dwOemId;
struct {
WORD wProcessorArchitecture;
WORD wReserved;
} ;
} ;
DWORD dwPageSize;
LPVOID lpMinimumApplicationAddress;
LPVOID lpMaximumApplicationAddress;
DWORD_PTR dwActiveProcessorMask;
DWORD dwNumberOfProcessors;
DWORD dwProcessorType;
DWORD dwAllocationGranularity;
WORD wProcessorLevel;
WORD wProcessorRevision;
} SYSTEM_INFO;
这是来自 MSDN，我尝试使用 10 和 12 个参数调用此函数 （古普塔不支持结构）。
在 32 位上我得到：

在 64 位上我得到：
替代文本 http://img691.imageshack.us/img691/8978/64bit.gif< /a>
每次在 32 位上我都会得到 0 OemID 吗？或者更好的是在 64 位版本的 Windows 上填写 OemID everytiem？
谢谢帮助！！

i got a little problem:
im tring to get the architecture of the OS, the problem is my programming language doesnt support such functions. Therefore i need to read this information form an windows dll (like kernel32.dll)
i did try to get the infos with the functions GetNativeSystemInfo/GetVersionEx/GetSystemInfo.
Unfortunately i were not able to get the architecture :/
Are there some other Functions to read the architecture in any windows dll?
(it dosnt need to be kernel32 it can be any dll but it must exists in win xp+)
As info: im using Gupta (SQLWindows/Team devoloper)
Edit1:
typedef struct _SYSTEM_INFO {
union {
DWORD dwOemId;
struct {
WORD wProcessorArchitecture;
WORD wReserved;
} ;
} ;
DWORD dwPageSize;
LPVOID lpMinimumApplicationAddress;
LPVOID lpMaximumApplicationAddress;
DWORD_PTR dwActiveProcessorMask;
DWORD dwNumberOfProcessors;
DWORD dwProcessorType;
DWORD dwAllocationGranularity;
WORD wProcessorLevel;
WORD wProcessorRevision;
} SYSTEM_INFO;
thats the info from MSDN, i tried to call this Function with with 10 and 12 Parameters
(Gupta dosnt support structs).
On 32Bit i get:

on 64Bit i get:
alt text http://img691.imageshack.us/img691/8978/64bit.gif
do i get every time a 0 OemID on 32 bit? or better is the OemID everytiem filled on 64bit version of windows?
Thx for help!!

GetNativeSystemInfo是绝对是要使用的功能。如果您的应用是本机 64 位应用，则GetNativeSystemInfo与GetSystemInfo;否则，如果它在WOW64下运行，它将返回真实的系统属性，即使它是在模拟的32位环境中运行。GetNativeSystemInfo填充SYSTEM_INFO结构，其中的wProcessorArchitecture成员告诉您系统是 32 位（可能是PROCESSOR_ARCHITECTURE_INTEL）还是 64 位（可能是 <代码>PROCESSOR_ARCHITECTURE_AMD64）。如果您的语言没有此 Win API 函数的包装器，要使用它，您可以照常使用
LoadLibrary和GetProcAddress，并且需要定义当然是 SYSTEM_INFO结构。更新
定义
我会在（常见）32 位系统上 Then
wProcessorArchitecture = 0，在（常见）64 位系统上定义wProcessorArchitecture = 9。这些分别是常量PROCESSOR_ARCHITECTURE_INTEL和PROCESSOR_ARCHITECTURE_AMD64。这些是常见的 32 位和 64 位架构。PROCESSOR_ARCHITECTURE_IA64 = 6稍微不常见一些，PROCESSOR_ARCHITECTURE_UNKNOWN = 65535也是如此。更新
是的，我看到你的问题。在 C 语言中，
union表示您一次选择一个选项。也就是说，结构是或
因为一个 DWORD 由与两个字 (2×2) 一样多的字节 (4) 组成，所以替代方案只是寻址（和命名）数据的两种方式整个结构。在我们的例子中，我们对
wProcessorArchitecture一词更感兴趣，而不是wProcessorArchitecture的增强dwOemId和完全无趣的wReserved代码>话。GetNativeSystemInfois definitely the function to use. If your app is a native 64-bit app,GetNativeSystemInfois the same asGetSystemInfo; otherwise, if it runs under WOW64, it will return the true system properties, even if it is run in an emulated 32-bit environment.GetNativeSystemInfofills aSYSTEM_INFOstructure, thewProcessorArchitecturemember of which tells you whether the system is 32-bit (probablyPROCESSOR_ARCHITECTURE_INTEL) or 64-bit (probablyPROCESSOR_ARCHITECTURE_AMD64).If your language does not have a wrapper for this Win API function, to use it, you can employ
LoadLibraryandGetProcAddressas usual, and you need to define theSYSTEM_INFOstructure, of course.Update
I would define
Then
wProcessorArchitecture = 0on a (common) 32-bit system, andwProcessorArchitecture = 9on a (common) 64-bit system. These are just the constantsPROCESSOR_ARCHITECTURE_INTELandPROCESSOR_ARCHITECTURE_AMD64, respectively. These are the common 32-bit and 64-bit architectures.PROCESSOR_ARCHITECTURE_IA64 = 6is slightly more uncommon, as is surelyPROCESSOR_ARCHITECTURE_UNKNOWN = 65535.Update
Yes, I see your problem. In C,
unionmeans that you choose one of the options at a time. That is, the structure is eitheror
Because one DWORD consists of as many bytes (4) as two words (2×2), the alternatives are just two ways of adressing (and naming) the data of the entire structure. In our case, we are more interested in the
wProcessorArchitectureword rather then the augmentdwOemIdofwProcessorArchitectureand the utterly uninterestingwReservedwords.我想你确实喜欢这样
