typedef struct _SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX {
LOGICAL_PROCESSOR_RELATIONSHIP Relationship;
DWORD Size;
union {
PROCESSOR_RELATIONSHIP Processor;
NUMA_NODE_RELATIONSHIP NumaNode;
CACHE_RELATIONSHIP Cache;
GROUP_RELATIONSHIP Group;
};
} SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX, *PSYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX;
Members
- Relationship
-
The type of relationship between the logical processors. This parameter can be one of the following LOGICAL_PROCESSOR_RELATIONSHIP values.
- Size
-
The size of the structure.
- Processor
-
A PROCESSOR_RELATIONSHIP structure that describes processor affinity. This structure contains valid data only if the Relationship member is RelationProcessorCore or RelationProcessorPackage.
- NumaNode
-
