Functions

WDF_FDO_EVENT_CALLBACKS_INIT The WDF_FDO_EVENT_CALLBACKS_INIT function initializes a WDF_FDO_EVENT_CALLBACKS structure.
WdfFdoAddStaticChild The WdfFdoAddStaticChild method adds a specified device to a function driver's list of child devices that have been identified by static enumeration.
WdfFdoGetDefaultChildList The WdfFdoGetDefaultChildList method returns a handle to a specified device's default child list.
WdfFdoInitAllocAndQueryProperty The WdfFdoInitAllocAndQueryProperty method allocates a buffer and retrieves a specified device property.
WdfFdoInitAllocAndQueryPropertyEx The WdfFdoInitAllocAndQueryPropertyEx method allocates a buffer and retrieves a specified device property.
WdfFdoInitOpenRegistryKey The WdfFdoInitOpenRegistryKey method opens a device's hardware key or a driver's software key in the registry and creates a framework registry-key object that represents the registry key.
WdfFdoInitQueryProperty The WdfFdoInitQueryProperty method retrieves a specified device property.
WdfFdoInitQueryPropertyEx The WdfFdoInitQueryPropertyEx method retrieves a specified device property.
WdfFdoInitSetDefaultChildListConfig The WdfFdoInitSetDefaultChildListConfig method configures a bus driver's default child list.
WdfFdoInitSetEventCallbacks The WdfFdoInitSetEventCallbacks method registers a framework-based function driver's event callback functions, for a specified device.
WdfFdoInitSetFilter The WdfFdoInitSetFilter method identifies the calling driver as an upper-level or lower-level filter driver, for a specified device.
WdfFdoInitWdmGetPhysicalDevice The WdfFdoInitWdmGetPhysicalDevice method retrieves a device's WDM physical device object (PDO).
WdfFdoLockStaticChildListForIteration The WdfFdoLockStaticChildListForIteration method prepares the framework for retrieving items from the static child list that belongs to a specified parent device.
WdfFdoQueryForInterface The WdfFdoQueryForInterface method obtains access to another driver's GUID-identified interface.
WdfFdoRetrieveNextStaticChild The WdfFdoRetrieveNextStaticChild method retrieves a handle to the next framework device object in a list of child devices.
WdfFdoUnlockStaticChildListFromIteration The WdfFdoUnlockStaticChildListFromIteration method unlocks the list of child devices for a specified device and processes any changes to the list that the driver made while the list was locked.

Callback functions

EVT_WDF_DEVICE_FILTER_RESOURCE_REQUIREMENTS A driver's EvtDeviceFilterAddResourceRequirements event callback function can add resources to a set of hardware resource requirements before the system assigns resources to a device.
EVT_WDF_DEVICE_REMOVE_ADDED_RESOURCES A driver's EvtDeviceRemoveAddedResources event callback function removes hardware resources that the driver's EvtDeviceFilterAddResourceRequirements callback function added.

Structures

WDF_FDO_EVENT_CALLBACKS The WDF_FDO_EVENT_CALLBACKS structure contains pointers to a function driver's PnP event callback functions.
