WDF_DEVICE_INTERFACE_PROPERTY_DATA_INIT function
[Applies to UMDF only]
The WDF_DEVICE_INTERFACE_PROPERTY_DATA_INIT function initializes a driver's WDF_DEVICE_INTERFACE_PROPERTY_DATA structure.
Syntax
void WDF_DEVICE_INTERFACE_PROPERTY_DATA_INIT( _In_ PWDF_DEVICE_INTERFACE_PROPERTY_DATA PropertyData, _In_ const GUID *InterfaceClassGUID, _In_ const DEVPROPKEY *PropertyKey );
Parameters
- PropertyData [in]
-
A pointer to WDF_DEVICE_INTERFACE_PROPERTY_DATA structure.
- InterfaceClassGUID [in]
-
A pointer to a GUID that identifies the device interface class.
- PropertyKey [in]
-
A pointer to a DEVPROPKEY structure that specifies the device property key.
Return value
This function does not return a value.
Remarks
Before calling the following methods, a driver must call WDF_DEVICE_INTERFACE_PROPERTY_DATA_INIT to initialize a WDF_DEVICE_INTERFACE_PROPERTY_DATA structure.
- WdfDeviceAllocAndQueryInterfaceProperty
- WdfDeviceAssignInterfaceProperty
- WdfDeviceQueryInterfaceProperty
The WDF_DEVICE_INTERFACE_PROPERTY_DATA_INIT function zeros the specified WDF_DEVICE_INTERFACE_PROPERTY_DATA structure and sets the structure's Size member. It also sets the structure's InterfaceClassGUID and PropertyKey members to the specified values.
For a code example that uses WDF_DEVICE_INTERFACE_PROPERTY_DATA_INIT, see WdfDeviceAssignInterfaceProperty.
