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 CE version 2.10, the major version number is 2.
dwMinorVersion
Identifies the minor version number of the operating system. For example, for Windows CE version 2.10, the minor version number is 1.
dwBuildNumber
Identifies the build number of the operating system or is set to 0.
dwPlatformId
Identifies the operating system platform. This member can be one of the following values:
| Value | Description |
| 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. |
| VER_PLATFORM_WIN32_CE | Win32 on Windows CE. |
