用GetVersionEx()具体返回信息参见下面结构的说明。
OSVERSIONINFO
The OSVERSIONINFO data structure contains operating system version information. The information includes major and minor version numbers, a build number, a platform identifier, and descriptive text about the operating system. This structure is used with the GetVersionEx function.
typedef struct _OSVERSIONINFO{
DWORD dwOSVersionInfoSize;
DWORD dwMajorVersion;
DWORD dwMinorVersion;
DWORD dwBuildNumber;
DWORD dwPlatformId;
TCHAR szCSDVersion[ 128 ];
} OSVERSIONINFO;
Members
dwOSVersionInfoSize
Specifies the size, in bytes, of this data structure. Set this member to sizeof(OSVERSIONINFO) before calling the GetVersionEx function.
dwMajorVersion
Identifies the major version number of the operating system. For example, for Windows NT version 3.51, the major version number is 3; and for Windows NT version 4.0, the major version number is 4.
dwMinorVersion
Identifies the minor version number of the operating system. For example, for Windows NT version 3.51, the minor version number is 51; and for Windows NT version 4.0, the minor version number is 0.
dwBuildNumber
Windows NT/2000: Identifies the build number of the operating system.
Windows 95/98: Identifies the build number of the operating system in the low-order word. The high-order word contains the major and minor version numbers.
dwPlatformId
Identifies the operating system platform. This member can be one of the following values: Value Platform
VER_PLATFORM_WIN32s Win32s on Windows 3.1.
VER_PLATFORM_WIN32_WINDOWS Win32 on Windows 95 or Windows 98.
For Windows 95, dwMinorVersion is zero.
For Windows 98, dwMinorVersion is greater than zero.
VER_PLATFORM_WIN32_NT Win32 on Windows NT/Windows 2000.
szCSDVersion
Windows NT/2000: Contains a null-terminated string, such as "Service Pack 3", that indicates the latest Service Pack installed on the system. If no Service Pack has been installed, the string is empty.
Windows 95/98: Contains a null-terminated string that provides arbitrary additional information about the operating system.
