Identifying Devices Uniquely

  • Article

You may need to implement a mechanism to uniquely identify a Windows CE–based device. For example, you may need to identify each cell phone that runs your OS image for billing and security purposes. Windows 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.
