BUS_RESOURCE_UPDATE_INTERFACE structure (wdm.h)

Enables device drivers to make direct calls to parent bus driver routines. This structure defines the GUID_BUS_RESOURCE_UPDATE_INTERFACE interface.

Syntax

typedef struct _BUS_RESOURCE_UPDATE_INTERFACE {
 USHORT Size;
 USHORT Version;
 PVOID Context;
 PINTERFACE_REFERENCE InterfaceReference;
 PINTERFACE_DEREFERENCE InterfaceDereference;
 PGET_UPDATED_BUS_RESOURCE GetUpdatedBusResource;
} BUS_RESOURCE_UPDATE_INTERFACE, *PBUS_RESOURCE_UPDATE_INTERFACE;

Members

Size

The size, in bytes, of this structure.

Version

The driver-defined interface version. Current version is PCI_FPB_RESOURCE_UPDATE_INTERFACE_VERSION.

Context

A pointer to interface-specific context information.

InterfaceReference

A pointer to an InterfaceReference routine that increments the interface's reference count.

InterfaceDereference

A pointer to an InterfaceDereference routine that decrements the interface's reference count.

GetUpdatedBusResource

A pointer to the busdriver-implemented callback function that is invoked to retrieve the updated resource information. See GET_UPDATED_BUS_RESOURCE

Remarks

The BUS_RESOURCE_UPDATE_INTERFACE structure is an extension of the INTERFACE structure.
