==Parameters==
==Parameters==
''void *memory''
''struct libbenchmark_topology_state *ts''
: A pointer to an allocation returned by ''benchmark_pal_numa_malloc''.
: A pointer a ''struct libbenchmark_topology'' obtained from ''libbenchmark_pal_populate_topology''.
 
''lfds711_pal_uint_t logical_processor_number''
: The logical processor number of the logical processor to add to the topology tree pointed to by ''ts''.
 
''enum flag windows_processor_group_inuse_flag''
: An ''enum flag'' which indicates whether or not the ''windows_processor_group_number'' argument contains a valid value (for that field is only meaningful on Windows 7 and greater).


''lfds711_pal_uint_t size_in_bytes''
''lfds711_pal_uint_t windows_processor_group_number''
: The number of bytes in the allocation pointed to by ''memory''.  Some NUMA ''free'' functions require this information, so the abstraction has to support it.
: The Windows processor group number of the logical processor to add to the topology tree pointed to by ''ts''.  This value is only meaningful on Windows 7 and greater.  It will only be used if the ''windows_processor_group_inuse_flag'' is set to ''RAISED'', and so if not used, can be set to any value.  Zero is as good a choice as any other.

==Notes==
Returns an allocation made by ''libbenchmark_pal_numa_malloc'' to the system.
This helper function is used by ''libbenchmark_pal_populate_topology'' to add a logical processor node to the topology tree.

                                                                               lfds711_pal_uint_t logical_processor_number,

Parameters

struct libbenchmark_topology_state *ts

A pointer a struct libbenchmark_topology obtained from libbenchmark_pal_populate_topology.

lfds711_pal_uint_t logical_processor_number

The logical processor number of the logical processor to add to the topology tree pointed to by ts.

enum flag windows_processor_group_inuse_flag

An enum flag which indicates whether or not the windows_processor_group_number argument contains a valid value (for that field is only meaningful on Windows 7 and greater).

lfds711_pal_uint_t windows_processor_group_number

The Windows processor group number of the logical processor to add to the topology tree pointed to by ts. This value is only meaningful on Windows 7 and greater. It will only be used if the windows_processor_group_inuse_flag is set to RAISED, and so if not used, can be set to any value. Zero is as good a choice as any other.

Return Value

No return value.

Example

Notes

This helper function is used by libbenchmark_pal_populate_topology to add a logical processor node to the topology tree.
