NUMA_NODE_RELATIONSHIP structure (winnt.h)

Represents information about a NUMA node in a processor group. This structure is used with the GetLogicalProcessorInformationEx function.

Syntax

typedef struct _NUMA_NODE_RELATIONSHIP {
  DWORD NodeNumber;
  BYTE  Reserved[18];
  WORD  GroupCount;
  union {
    GROUP_AFFINITY GroupMask;
    GROUP_AFFINITY GroupMasks[ANYSIZE_ARRAY];
  } DUMMYUNIONNAME;
} NUMA_NODE_RELATIONSHIP, *PNUMA_NODE_RELATIONSHIP;

Members

NodeNumber

The number of the NUMA node.

Reserved[18]

The number of groups included in the GroupMasks array. This field was introduced in TBD Release Iron. On earlier versions, this value is always 0.

DUMMYUNIONNAME

DUMMYUNIONNAME.GroupMask

A GROUP_AFFINITY structure that specifies a group number and processor affinity within the group.

DUMMYUNIONNAME.GroupMasks[ANYSIZE_ARRAY]

An array of GROUP_AFFINITY structure that specifies a group number and processor affinity within the group.
