Chapter 3 — Configuring the Computer

Syntax

BOOL KernelIoControl( IOCTL_HAL_GET_DEVICEID,LPVOID lpInBuf,DWORD nInBufSize,LPVOID lpOutBuf,DWORD nOutBufSize,LPDWORD lpBytesReturned );

Parameters

lpInBuf	Should be set to NULL. STRICT_ID settings are not supported.
lpInBufSize	Should be set to zero.
lpOutBuf	Must point to a UNIQUE_DEVICEID structure as defined by
	DEVICEID.H if the UUID is to be returned
nOutBufSize	The size of the UNIQUE_DEVICEID in bytes if the UUID is to
	be returned. A DEVICE_ID as defined by PKFUNCS.H is
	returned if the size in bytes is greater than or equal to
	sizeof(DEVICE_ID).
lpBytesReturned	The number of bytes returned by the function.

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_GET_OAL_VERINFO

Returns the HAL version information of the Pocket PC image.

Usage

#include “oemioctl.h”

Syntax

BOOL KernelIoControl( IOCTL_HAL_GET_OAL_VERINFO,LPVOID lpInBuf,DWORD nInBufSize,LPVOID lpOutBuf,DWORD nOutBufSize,LPDWORD lpBytesReturned );

Parameters

lpInBuf	Should be set to NULL.
lpInBufSize	Should be set to zero.
lpOutBuf	Must point to a VERSIONINFO structure as defined by
	OEMIOCTL.H. The fields should have these values:
	•	cboemverinfo	sizeof (tagOemVerInfo);
	•	verinfover	1
	•	sig;	“ITC\0”
	•	id;	‘N’
	•	tgtcustomer	“”
	•	tgtplat	SeaRay
	•	tgtplatversion	Current build version number
	•	tgtcputype[8];	“Intel\0”
	•	tgtcpu	“PXA255\0”;
	•	tgtcoreversion	“”
	•	date	Build time
	•	time	Build date
nOutBufSize	The size of VERSIONINFO in bytes.
lpBytesReturned	Returns sizeof(PVERSIONINFO).
