擷取系統版本資訊 GetVersionEx

擷取系統版本資訊

BOOL GetVersionEx(LPOSVERSIONINFO lpVersionInformation);

參數說明：

lpVersionInformation指向一個OSVERSIONINFO資料結構的指針，用于填充作業系統版本資訊。

在調用GetVersionEx函數之前，先将OSVERSIONINFO資料結構的dwOSVersionInfoSize成員設定為為sizeof（OSVERSIONINFO）。

傳回值：

如果函數成功，傳回值為非零。

如果函數失敗，傳回值為零。為了獲得更多錯誤資訊，可調用GetLastError函數。如果您給OSVERSIONINFO結構體的dwOSVersionInfoSize成員指定一個無效值，函數将失敗。

備注：

該GetVersionEx函數取代了GetVersion函數的功能，它是獲得作業系統版本号資訊的首選方法。新的應用程式應該使用GetVersionEx函數，而不是GetVersion函數。

先列出OSVERSIONINFO結構，用于表示版本資訊

typedef struct _OSVERSIONINFOA {
    DWORD dwOSVersionInfoSize;  //結構體大小
    DWORD dwMajorVersion;          //主版本号
    DWORD dwMinorVersion;          //次版本号
    DWORD dwBuildNumber;          //建構号
    DWORD dwPlatformId;              //平台相關資訊
    CHAR   szCSDVersion[ 128 ];     // 版本維護資訊
} OSVERSIONINFOA, *POSVERSIONINFOA, *LPOSVERSIONINFOA;
typedef struct _OSVERSIONINFOW {
    DWORD dwOSVersionInfoSize;
    DWORD dwMajorVersion;
    DWORD dwMinorVersion;
    DWORD dwBuildNumber;
    DWORD dwPlatformId;
    WCHAR  szCSDVersion[ 128 ];     // Maintenance string for PSS usage
} OSVERSIONINFOW, *POSVERSIONINFOW, *LPOSVERSIONINFOW;
#ifdef UNICODE
typedef OSVERSIONINFOW OSVERSIONINFO;
typedef POSVERSIONINFOW POSVERSIONINFO;
typedef LPOSVERSIONINFOW LPOSVERSIONINFO;
#else
typedef OSVERSIONINFOA OSVERSIONINFO;
typedef POSVERSIONINFOA POSVERSIONINFO;
typedef LPOSVERSIONINFOA LPOSVERSIONINFO;
#endif // UNICODE

typedef struct _OSVERSIONINFOEXA {
    DWORD dwOSVersionInfoSize;
    DWORD dwMajorVersion;
    DWORD dwMinorVersion;
    DWORD dwBuildNumber;
    DWORD dwPlatformId;
    CHAR   szCSDVersion[ 128 ];     // Maintenance string for PSS usage
    WORD wServicePackMajor;
    WORD wServicePackMinor;
    WORD wReserved[2];
} OSVERSIONINFOEXA, *POSVERSIONINFOEXA, *LPOSVERSIONINFOEXA;
typedef struct _OSVERSIONINFOEXW {
    DWORD dwOSVersionInfoSize;
    DWORD dwMajorVersion;
    DWORD dwMinorVersion;
    DWORD dwBuildNumber;
    DWORD dwPlatformId;
    WCHAR  szCSDVersion[ 128 ];     // Maintenance string for PSS usage
    WORD wServicePackMajor;
    WORD wServicePackMinor;
    WORD wReserved[2];
} OSVERSIONINFOEXW, *POSVERSIONINFOEXW, *LPOSVERSIONINFOEXW;

//
// dwPlatformId 的定義:
//

#define VER_PLATFORM_WIN32s             0
#define VER_PLATFORM_WIN32_WINDOWS      1
#define VER_PLATFORM_WIN32_NT           2

	}

	printf("%s\n",szVersionInfo);
	printf("OS Version:%d.%d Build %d",ovex.dwMajorVersion,ovex.dwMinorVersion,
