![]() ![]() Requests the name of the enumerator for the device, such as "PCI" or "root". ![]() PropertyBuffer points to a NULL-terminated WCHAR string. Requests the name of the driver-specific registry key. Requests a string describing the device, such as "Microsoft PS/2 Port Mouse", typically defined by the manufacturer. PropertyBuffer points to a REG_MULTI_SZ value. Requests the compatible IDs reported by the device. Requests the name of the device's setup class, in text format. This routine returns the GUID in a string format as follows, where each "c" represents a hexadecimal character: DevicePropertålassName PropertyBuffer points to a NULL-terminated array of WCHAR. Requests the GUID for the device's setup class. PropertyBuffer points to a GUID, which is a 16-byte structure that contains the GUID in binary form. The system-defined bus type GUIDs are listed in the Wdmguid.h header file. Requests the GUID for the bus that the device is connected to. Requests the legacy bus number of the bus the device is connected to. PropertyBuffer points to a CM_RESOURCE_LIST structure. The hardware resources assigned to the device by the firmware, in translated form. DevicePropertyBootConfigurationTranslated ![]() Requests the hardware resources assigned to the device by the firmware, in raw form. ![]() An address value of 0xFFFFFFFF indicates that the underlying bus driver did not supply a bus address for the device. The caller of this routine should call the routine again to request the DevicePropertyBusTypeGuid, or possibly the DevicePropertyLegacyBusType, so it can interpret the address. The interpretation of this address is bus-specific. Requests the address of the device on the bus. Must be one of the following DEVICE_REGISTRY_PROPERTY enumeration values: DevicePropertyAddress Specifies the device property being requested. Pointer to the physical device object (PDO) for the device being queried. DEVICE_REGISTRY_PROPERTY DeviceProperty, The IoGetDeviceProperty routine retrieves information about a device such as configuration information and the name of its PDO. ![]()
