The NdisGetProcessorInformation function retrieves information about the CPU topology of the local computer and the set of processors that a miniport driver must use for receive side scaling (RSS).
NDIS_STATUS NdisGetProcessorInformation( PNDIS_SYSTEM_PROCESSOR_INFO SystemProcessorInfo );
A pointer to an NDIS_SYSTEM_PROCESSOR_INFO structure that NDIS fills with the information about the CPU topology of the system and the RSS processor set.
NdisGetProcessorInformation can return one of the following status values:
||The operation completed successfully.|
||The size that was specified in the Header.Size member of the SystemProcessorInfo parameter was too small.|
NDIS drivers call the NdisGetProcessorInformation function to retrieve information about the processors on the local computer.
RSS-capable miniport drivers that support MSI-X call NdisGetProcessorInformation in their MiniportFilterResourceRequirements function. Miniport drivers set the interrupt affinity of the allocated MSI-X messages to the RSS processors that are specified in the RssProcessors member of the SystemProcessorInfo parameter.
|Windows version||Supported in NDIS 6.0 and 6.1. For NDIS 6.20 and later, ise NdisGetProcessorInformationEx or NdisGetRssProcessorInformation instead.|
