NDIS_SYSTEM_PROCESSOR_INFO_EX structure (ntddndis.h)
The NDIS_SYSTEM_PROCESSOR_INFO_EX structure specifies information about the CPU topology of the local computer.
Syntax
typedef struct _NDIS_SYSTEM_PROCESSOR_INFO_EX {
NDIS_OBJECT_HEADER Header;
ULONG Flags;
NDIS_PROCESSOR_VENDOR ProcessorVendor;
ULONG NumSockets;
ULONG NumCores;
ULONG NumCoresPerSocket;
ULONG MaxHyperThreadingProcsPerCore;
ULONG ProcessorInfoOffset;
ULONG NumberOfProcessors;
ULONG ProcessorInfoEntrySize;
} NDIS_SYSTEM_PROCESSOR_INFO_EX, *PNDIS_SYSTEM_PROCESSOR_INFO_EX;
Members
Header
The NDIS_OBJECT_HEADER structure for the NDIS_SYSTEM_PROCESSOR_INFO_EX structure. NDIS sets the Type member of the structure that Header specifies to NDIS_OBJECT_TYPE_DEFAULT, the Revision member to NDIS_SYSTEM_PROCESSOR_INFO_EX_REVISION_1, and the Size member to NDIS_SIZEOF_SYSTEM_PROCESSOR_INFO_EX_REVISION_1.
Flags
Reserved. NDIS sets this member to zero.
ProcessorVendor
The processor vendor specified as one of the values from the NDIS_PROCESSOR_VENDOR enumeration.
NumSockets
The total number of processor physical packages (that is, sockets on the local computer motherboard) that are in the local computer.
NumCores
The total number of core processors that are in the local computer. For example, set this member to four if there are two dual core physical packages.
NumCoresPerSocket
The number of core processors that are in each physical package. For example, set this member to two for a dual core physical package.
MaxHyperThreadingProcsPerCore
The maximum number of logical processors that are in each hyper-threaded core processor. For example, set this member to two if each hyper-threaded core processor supports two logical processors.
ProcessorInfoOffset
The offset, in bytes, from the start of the structure to an array of NDIS_PROCESSOR_INFO_EX structures, with each entry describing a processor on the computer. The NumberOfProcessors member contains the number of NDIS_PROCESSOR_INFO_EX structures in the array. The ProcessorInfoEntrySize member contains the size of the NDIS_PROCESSOR_INFO_EX structures in the array.
NumberOfProcessors
The number of elements in the array of NDIS_PROCESSOR_INFO_EX structures that follows this structure.
ProcessorInfoEntrySize
The size, in bytes, of elements in the array of NDIS_PROCESSOR_INFO_EX structures that follows this structure.
Remarks
NDIS network drivers use the NDIS_SYSTEM_PROCESSOR_INFO_EX structure in calls to the NdisGetProcessorInformationEx function. After NdisGetProcessorInformationEx returns, this structure contains information about the CPU topology of the system.
