bootstrap loader
S tgtcputype[8]; “Intel\0”;
S tgtcpu “PXA255\0”
S tgtcoreversion “”
S date Build time
S time Build date
nOutBufSize ThesizeofVERSIONINFOinbytes.
lpBytesReturned The nu mber of bytes re turned to lpOutBuf.
Return Values
Returns TRUE if function succeeds. Returns FALSE if the function fails.
GetLastError() may be used to get the extended error value.
IOCTL_HAL_WARMBOOT
Causes the system to perform a warm-boot. The object store is retained.
Usage
#include “oemioctl.h”
Syntax
BOOL KernelIoControl( IOCTL_HAL_WARMBOOT,LPVOID lpInBuf,DWORD
nInBufSize,LPVOID lpOutBuf,DWORD nOutBufSize,LPDWORD lpBytesReturned );
Parameters
lpInBuf Should be set to NULL.
lpInBufSize Should be set to zero.
lpOutBuf Should be NULL.
nOutBufSize Should be zero.
Return Values
None.
IOCTL_HAL_COLDBOOT
Causes the system to perform a cold-boot. The object store is cleared.
Usage
#include “oemioctl.h”
Syntax
BOOL KernelIoControl( IOCTL_HAL_COLDBOOT,LPVOID lpInBuf,DWORD
nInBufSize,LPVOID lpOutBuf,DWORD nOutBufSize,LPDWORD lpBytesReturned );
