Usage

#include “pkfuncs.h”

Syntax
BOOL KernelIoControl( IOCTL_PROCESSOR_INFORMATION,LPVOID
lpInBuf,DWORD nInBufSize,LPVOID lpOutBuf,DWORD
nOutBufSize,LPDWORD lpBytesReturned );
Parameters
lpInBuf Should be set to NULL.
nInBufSize Should be set to zero.
lpOutBuf Should bea pointer to the PROCESSOR_INFO structure.The
PROCESSOR_INFO structure stores information that describes
the CPU moredes criptively.
typedef __PROCESSOR_INFO {
WORD wVersion; // Set to value 1
WCHAR szProcessorCore[40]; // “ARM\0”
WORD wCoreRevision; // 4
WCHAR szProcessorName[40]; // “PXA255\0”
WORD wProcessorRevision; // 0
WCAHR szCatalogNumber[100]; // 0
WCHAR szVendor[100]; // “Intel Corporation\0”
DWORD dwInstructionSet; // 0
DWORD dwClockSpeed; // 400
}
nOutBufSize Should be set to sizeof(PROCESSOR_INFO)in bytes.
lpBytesReturned Returnssizeof(PROCESSOR_INFO);
ReturnValues
Returns TRUE if function succeeds. Returns FALSE if the function fails.
GetLastError() may be used to get the extende d error value.
