@Structure.FieldOrder(value={"relationship","size"})
public abstract static class WinNT.SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX
extends Structure

Contains information about the relationships of logical processors and related hardware. The Kernel32.GetLogicalProcessorInformationEx(int, com.sun.jna.Pointer, com.sun.jna.platform.win32.WinDef.DWORDByReference) function uses this structure.

The native structure contains a union, which is mapped to JNA as subclasses.

Field Detail

relationship

public int relationship

The type of relationship between the logical processors. This parameter can be one of the following values: WinNT.LOGICAL_PROCESSOR_RELATIONSHIP.RelationCache, WinNT.LOGICAL_PROCESSOR_RELATIONSHIP.RelationGroup, WinNT.LOGICAL_PROCESSOR_RELATIONSHIP.RelationNumaNode, WinNT.LOGICAL_PROCESSOR_RELATIONSHIP.RelationProcessorCore, or WinNT.LOGICAL_PROCESSOR_RELATIONSHIP.RelationProcessorPackage.

This field identifies which subclass will be instantiated by the fromPointer(Pointer) method.

size

public int size

The size of the structure, in bytes.

Constructor Detail

SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX

public SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX()

SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX

protected SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX(Pointer memory)

This constructor should only be called by a subclass to ensure memory is properly allocated to the subclass fields.

Parameters:

memory - A pointer to the allocated native memory.

Method Detail

fromPointer

public static WinNT.SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX fromPointer(Pointer memory)

Create a new instance of the appropriate subclass of WinNT.SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX from the provided Pointer to native memory. Use this method rather than #SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX(Pointer) to properly cast the Pointer to the appropriate subclass and populate variable length arrays.

Parameters:

memory - A pointer to allocated memory to be cast to this class.

Returns:

An instance of the appropriate subclass depending on the value of the relationship field. If the relationship member is WinNT.LOGICAL_PROCESSOR_RELATIONSHIP.RelationProcessorCore or WinNT.LOGICAL_PROCESSOR_RELATIONSHIP.RelationProcessorPackage, the return type will be WinNT.PROCESSOR_RELATIONSHIP. If the relationship member is WinNT.LOGICAL_PROCESSOR_RELATIONSHIP.RelationNumaNode, the return type will be WinNT.NUMA_NODE_RELATIONSHIP. If the relationship member is WinNT.LOGICAL_PROCESSOR_RELATIONSHIP.RelationCache, the return type will be WinNT.CACHE_RELATIONSHIP. If the relationship member is WinNT.LOGICAL_PROCESSOR_RELATIONSHIP.RelationGroup, the return type will be WinNT.GROUP_RELATIONSHIP.
