} LOGICAL_PROCESSOR_RELATIONSHIP;

Constants

RelationProcessorCore

The specified logical processors share a single processor core.

RelationNumaNode

The specified logical processors are part of the same NUMA node.

RelationCache

The specified logical processors share a cache.

RelationProcessorPackage

The specified logical processors share a physical package (a single package socketed or soldered onto a motherboard may contain multiple processor cores or threads, each of which is treated as a separate processor by the operating system).

Windows Server 2003:  This value is not supported until Windows Server 2003 with SP1 and Windows XP Professional x64 Edition.

RelationGroup

The specified logical processors share a single processor group.

Windows Server 2008, Windows Vista, Windows Server 2003 and Windows XP Professional x64 Edition:  This value is not supported until Windows Server 2008 R2.

RelationAll

On input, retrieves information about all possible relationship types. This value is not used on output.
