## Interface WinNT.LOGICAL_PROCESSOR_RELATIONSHIP

- Enclosing interface:
    WinNT

      public static interface WinNT.LOGICAL_PROCESSOR_RELATIONSHIP

  Represents the relationship between the processor set identified in the corresponding `WinNT.SYSTEM_LOGICAL_PROCESSOR_INFORMATION` or `SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX` structure.

- - ### Field Summary

    Fields
    Modifier and Type | Field and Description
    --- | ---
    `static int` | `RelationAll` On input, retrieves information about all possible relation types.
    `static int` | `RelationCache` The specified logical processors share a cache.
    `static int` | `RelationGroup` The specified logical processors share a single processor group.
    `static int` | `RelationNumaNode` The specified logical processors are part of the same NUMA node.
    `static int` | `RelationNumaNodeEx` Introduced in Windows Server 2022 (21H2, build 20348).
    `static int` | `RelationProcessorCore` The specified logical processors share a single processor core.
    `static int` | `RelationProcessorDie` The specified logical processors share a single processor die.
    `static int` | `RelationProcessorModule` The specified logical processors share a single processor module.
    `static int` | `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.)

    - #### RelationNumaNode

          static final int RelationNumaNode

      The specified logical processors are part of the same NUMA node.
      See Also:
        Constant Field Values

    - #### RelationCache

          static final int RelationCache

      The specified logical processors share a cache.

      Not supported until Windows Server 2003 SP1 / Windows XP Professional x64.

      See Also:
        Constant Field Values

    - #### RelationProcessorPackage

          static final int 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.)

      Not supported until Windows Server 2003 SP1 / Windows XP Professional x64.

      See Also:
        Constant Field Values

    - #### RelationGroup

          static final int RelationGroup

      The specified logical processors share a single processor group.

      Not supported until Windows Server 2008 R2.

      See Also:
        Constant Field Values

    - #### RelationProcessorDie

          static final int RelationProcessorDie

      The specified logical processors share a single processor die.

        Constant Field Values

    - #### RelationNumaNodeEx

          static final int RelationNumaNodeEx

      Introduced in Windows Server 2022 (21H2, build 20348). Requests that the full affinity be returned. Unlike the other relation types, RelationNumaNodeEx is not used on input. It is simply a request for RelationNumaNode with full group information.

    - #### RelationAll

          static final int RelationAll

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

      Not supported until Windows Server 2008 R2.
