Device Information IOCTLs (Windows Embedded CE 6.0)
1/5/2010
The following table shows the device information IOCTLs.
Programming element | Description |
---|---|
This IOCTL returns device information using the system parameters information (SPI) codes supported by the SystemParametersInfo function. |
|
This IOCTL returns the current DEVICE_ID structure assigned to the device. This IOCTL is being deprecated, starting with Windows Embedded CE 6.0. Its functionality has been integrated into IOCTL_HAL_GET_DEVICE_INFO. For more information, see Device Information IOCTL Unification. |
|
This IOCTL retrieves a 64-bit random number based upon an OEM-defined device hardware identifier. |
|
This IOCTL returns the universally unique identifier (UUID). This IOCTL is being deprecated, starting with Windows Embedded CE 6.0. Its functionality has been integrated into IOCTL_HAL_GET_DEVICE_INFO. For more information, see Device Information IOCTL Unification. |
|
This IOCTL obtains information about the system parameters information (SPI) codes supported by the SystemParametersInfo function. |
|
This IOCTL queries the kernel for information about a preferred resolution for the system to use. It is used by the graphics device interface (GDI). |
|
This IOCTL sets the data returned by IOCTL_HAL_GET_DEVICE_INFO. |
|
This IOCTL retrieves microprocessor information from the OAL and stores it in the PROCESSOR_INFO structure. It is a request by an application. |
