WDF_DEVICE_PROPERTY_DATA structure (wdfdevice.h)

  • Article

[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:

Drivers should initialize this structure by calling WDF_DEVICE_PROPERTY_DATA_INIT.

Requirements
