GetNumaAvailableMemoryNode Function

Retrieves the amount of memory available in the specified node.

Use the GetNumaAvailableMemoryNodeEx function to specify the node as a USHORT value.

Syntax

C++

BOOL WINAPI GetNumaAvailableMemoryNode(
  __in   UCHAR Node,
  __out  PULONGLONG AvailableBytes
);

Parameters

Node [in]: The number of the node.
AvailableBytes [out]: The amount of available memory for the node, in bytes.

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

The GetNumaAvailableMemoryNode function returns the amount of memory consumed by free and zeroed pages on the specified node. This memory does not include standby pages. Therefore, the sum of the available memory values for all nodes in the system is equal to the value of the Free & Zero Page List Bytes memory performance counter rather than the Available Bytes memory performance counter, which does include standby pages. For more information about performance counters, see Memory Performance Information.

Minimum supported client	Windows Vista, Windows XP Professional x64 Edition, Windows XP with SP2
Minimum supported server	Windows Server 2003

I can't seem to get this function to give me an accurate ammount of memory associated with the node. Does anyone have an example of they can post?
