WDF_DEVICE_INTERFACE_PROPERTY_DATA structure
[Applies to UMDF only]
The WDF_DEVICE_INTERFACE_PROPERTY_DATA structure describes a device interface property.
Syntax
typedef struct _WDF_DEVICE_INTERFACE_PROPERTY_DATA { ULONG Size; const GUID *InterfaceClassGUID; PCUNICODE_STRING ReferenceString; const DEVPROPKEY *PropertyKey; LCID Lcid; ULONG Flags; } WDF_DEVICE_INTERFACE_PROPERTY_DATA, *PWDF_DEVICE_INTERFACE_PROPERTY_DATA;
Members
- Size
- 
The size, in bytes, of this structure. 
- InterfaceClassGUID
- 
A pointer to a GUID that identifies the device interface class. 
- ReferenceString
- 
A pointer to a UNICODE_STRING structure that describes a reference string for the device interface. This parameter is optional and can be NULL. 
- PropertyKey
- 
A pointer to a DEVPROPKEY structure that specifies the device property key. 
- Lcid
- 
Specifies a locale identifier. Set this parameter either to a language-specific LCID value or to LOCALE_NEUTRAL. The LOCALE_NEUTRAL LCID specifies that the property is language-neutral (that is, not specific to any language). Do not set this parameter to LOCALE_SYSTEM_DEFAULT or LOCALE_USER_DEFAULT. For more information about language-specific LCID values, see LCID Structure. 
- Flags
- 
Not currently used. Set this member to zero. 
Remarks
The WDF_DEVICE_INTERFACE_PROPERTY_DATA structure is used as input to the following methods:
- WdfDeviceAllocAndQueryInterfaceProperty
- WdfDeviceAssignInterfaceProperty
- WdfDeviceQueryInterfaceProperty
Drivers should initialize this structure by calling WDF_DEVICE_INTERFACE_PROPERTY_DATA_INIT.
Examples
For an example of how to use WDF_DEVICE_INTERFACE_PROPERTY_DATA, see WdfDeviceAssignInterfaceProperty.
