WDF_DEVICE_PROPERTY_DATA structure (wdfdevice.h)
[Applies to KMDF and UMDF]
The WDF_DEVICE_PROPERTY_DATA structure describes a device property.
Syntax
typedef struct _WDF_DEVICE_PROPERTY_DATA {
ULONG Size;
const DEVPROPKEY *PropertyKey;
LCID Lcid;
ULONG Flags;
} WDF_DEVICE_PROPERTY_DATA, *PWDF_DEVICE_PROPERTY_DATA;
Members
Size
The size, in bytes, of this structure.
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
Set to PLUGPLAY_PROPERTY_PERSISTENT if this property value is being set by WdfDeviceAssignProperty. Otherwise, set this member to zero.
Remarks
The WDF_DEVICE_PROPERTY_DATA structure is used as input to the following methods:
- WdfDeviceAllocAndQueryPropertyEx
- WdfDeviceAssignProperty
- WdfDeviceQueryPropertyEx
- WdfFdoInitAllocAndQueryPropertyEx
- WdfFdoInitQueryPropertyEx
Requirements
