GetNumaProcessorNode function
Retrieves the node number for the specified processor.
Use the GetNumaProcessorNodeEx function to specify a processor group and retrieve the node number as a USHORT value.
Syntax
BOOL WINAPI GetNumaProcessorNode( _In_ UCHAR Processor, _Out_ PUCHAR NodeNumber );
Parameters
- Processor [in]
-
The processor number.
On a system with more than 64 logical processors, the processor number is relative to the processor group that contains the processor on which the calling thread is running.
- NodeNumber [out]
-
The node number. If the processor does not exist, this parameter is 0xFF.
Return value
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
Remarks
To retrieve the list of processors on the system, use the GetProcessAffinityMask function.
Examples
For an example, see Allocating Memory from a NUMA Node.
