Usage
#include "oemioctl.h"
Syntax
BOOL KernelIoControl( IOCTL_GET_CPU_ID,LPVOID lpInBuf, DWORD
nInBufSize,LPVOID lpOutBuf,DWORD nOutBufSize,LPDWORD
lpBytesReturned );
Parameters
lpInBuf Should point to a CPUIdInfo structure defined in
OEMIOCTL.H.
lpInBufSize Should be sizeof(CPUIdInfo).
lpOutBuf Should be NULL.
nOutBufSize Should be set to 0.
lpBytesReturned Returns sizeof(PROCESSOR_INFO);
Return Values
Returns TRUE if function succeeds. Returns FALSE if the function fails.
GetLastError() may be used to get the extended error value.
There are several methods, via Kernel I/O Control functions, that an ap-
plication program can use to force the 700 Series Computer to reboot.
IOCTL_HAL_REBOOT performs a warm-boot. See page 278.
Invoking the KernelIOControl function with
IOCTL_HAL_COLDBOOT forces a cold reboot. This resets the 700
Series Computer and reloads Windows CE as if a power-up had been
performed. The contents of the Windows CE RAM-based object store are
discarded. See page 275.
This function is supported on the 700 Series Computers. It performs a
warm boot of the system, preserving the object store. See page 275.
