IOCTL_HAL_AUTHENTICATE_DEVICE (Compact 2013)
10/16/2014
This I/O control message is predefined for an OEM who wants to authenticate the device before the device is allowed to boot and be used by a user. Send this message with OEMIoControl.
Syntax
BOOL OEMIoControl(
DWORD dwIoControlCode, // use IOCTL_HAL_AUTHENTICATE_DEVICE
LPVOID lpInBuffer, // pointer to input buffer
DWORD nInBufferSize, // input buffer size
LPVOID lpOutBuffer, // pointer to output buffer
DWORD nOutBufferSize, // output buffer size
LPDWORD lpBytesReturned // number of bytes returned
);
Parameters
- dwIoControlCode
[in] Control code for the operation. Use IOCTL_HAL_AUTHENTICATE_DEVICE for this operation.
Remarks
The parameters are implemented by the OEM, and the return values are based on the OEM implementation. The data passed to the OAL is OEM-specific and depends on how the OEM wants to validate the run-time image running on the device.
An image can be encoded with a device's hardware ID so the image only runs on one device. When the device boots, an application can be run that will call this I/O control and pass information to the OAL so a comparison of values can be achieved.
