      extended by com.sun.jna.platform.win32.WinNT.OSVERSIONINFO
Enclosing interface:
WinNT

public static class WinNT.OSVERSIONINFO
extends Structure

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.

Major version number of the operating system.


dwMinorVersion

public WinDef.DWORD dwMinorVersion
Minor version number of the operating system.


dwBuildNumber

public WinDef.DWORD dwBuildNumber
Build number of the operating system.


dwPlatformId

public WinDef.DWORD dwPlatformId
Operating system platform.


szCSDVersion

public char[] szCSDVersion
Pointer to a null-terminated string, such as "Service Pack 3", that indicates the latest Service Pack installed on the system.

Method Detail

getFieldOrder

protected List getFieldOrder()
Description copied from class: Structure
Return this Structure's field names in their proper order. For example,

 protected List getFieldOrder() {
     return Arrays.asList(new String[] { ... });
 }
 
IMPORTANT When deriving from an existing Structure subclass, ensure that you augment the list provided by the superclass, e.g.

 protected List getFieldOrder() {
     List fields = new ArrayList(super.getFieldOrder());
     fields.addAll(Arrays.asList(new String[] { ... }));
     return fields;
 }
 
Field order must be explicitly indicated, since the field order as returned by Class.getFields() is not guaranteed to be predictable.
