The ReadProcessorSystemData method returns data about the specified processor.
HRESULT ReadProcessorSystemData( ULONG Processor, ULONG Index, PVOID Buffer, ULONG BufferSize, PULONG DataSize );
Specifies the processor whose data is to be read.
Specifies the data type to read. The following table contains the valid values. After successful completion, the data returned in the buffer Buffer has the type specified by the middle column.
|DEBUG_DATA_KPCR_OFFSET||Returns the virtual address of the processor's Processor Control Region (PCR). In this case, the argument Buffer can be considered to have type PULONG64.|
|DEBUG_DATA_KPRCB_OFFSET||Returns the virtual address of the processor's Processor Control Block (PRCB). In this case, the argument Buffer can be considered to have type PULONG64.|
|DEBUG_DATA_KTHREAD_OFFSET||Returns the virtual address of the KTHREAD structure for the system thread running on the processor. In this case, the argument Buffer can be considered to have type PULONG64.|
|DEBUG_DATA_BASE_TRANSLATION_VIRTUAL_OFFSET||Returns the virtual address of the base of the paging information owned by the operating system or the processor. The address and the content at the address are processor- and operating-system-dependent. In this case, the argument Buffer can be considered to have type PULONG64.|
|DEBUG_DATA_PROCESSOR_IDENTIFICATION||Returns a description of the processor. In this case, the argument Buffer can be considered to have type PDEBUG_PROCESSOR_IDENTIFICATION_ALL .|
|DEBUG_DATA_PROCESSOR_SPEED||Returns the speed of the processor in MHz. This may not work in a particular session. In this case, the argument Buffer can be considered to have type PULONG.|
Receives the processor data. Upon successful completion of the method, the contents of this buffer may be accessed by casting Buffer to the type specified in the above table.
Specifies the size in bytes of the buffer Buffer. This is the maximum number of bytes that will be returned.
Receives the size of the data in bytes. If DataSize is NULL, this information is not returned.
||The method was successful.|
This method can also return error values. See Return Values for more details.
This method is only available in kernel-mode debugging.
