WDF_DEVICE_PROPERTY_DATA_INIT function (wdfdevice.h)

[Applies to KMDF and UMDF]

The WDF_DEVICE_PROPERTY_DATA_INIT function initializes a driver's WDF_DEVICE_PROPERTY_DATA structure.

Syntax

void WDF_DEVICE_PROPERTY_DATA_INIT(
  [in] PWDF_DEVICE_PROPERTY_DATA PropertyData,
  [in] const DEVPROPKEY          *PropertyKey
);

Parameters

[in] PropertyData

A pointer to WDF_DEVICE_PROPERTY_DATA structure.

[in] PropertyKey

A pointer to a DEVPROPKEY structure that specifies the device property key.

Return value

None

Remarks

Before calling the following methods, a driver must call WDF_DEVICE_PROPERTY_DATA_INIT to initialize a WDF_DEVICE_PROPERTY_DATA structure.

• WdfDeviceAllocAndQueryPropertyEx
• WdfDeviceAssignProperty
• WdfDeviceQueryPropertyEx
• WdfFdoInitAllocAndQueryPropertyEx
• WdfFdoInitQueryPropertyEx

The WDF_DEVICE_PROPERTY_DATA_INIT function zeros the specified WDF_DEVICE_PROPERTY_DATA structure and sets the structure's Size member. It also sets the structure's PropertyKey member to the specified value.
