You may need to implement a mechanism to uniquely identify a Windows Embedded CE–based device. For example, you may need to identify each cell phone that runs your run-time image for billing and security purposes.
Windows Embedded CE uses the DEVICE_ID structure to hold the unique device identification number.
You can implement the I/O control code IOCTL_HAL_GET_DEVICEID in OEMIoControl to return DEVICE_ID to an application.
**Starting with Windows Embedded CE 6.0, IOCTL_HAL_GET_DEVICEID has been deprecated and the functionality has been extented into IOCTL_HAL_GET_DEVICE_INFO.
For more information, see Device Information IOCTL Unification.**
