wdfpdo.h contains the following programming interfaces:

Functions

WDF_PDO_EVENT_CALLBACKS_INIT The WDF_PDO_EVENT_CALLBACKS_INIT function initializes a WDF_PDO_EVENT_CALLBACKS structure.
WdfPdoAddEjectionRelationsPhysicalDevice The WdfPdoAddEjectionRelationsPhysicalDevice method indicates that a specified device is ejected when another specified device is ejected.
WdfPdoClearEjectionRelationsDevices The WdfPdoClearEjectionRelationsDevices method removes all devices from the list of devices that must be ejected when a specified device is ejected.
WdfPdoGetParent The WdfPdoGetParent method returns a handle to the framework device object that represents the parent device of a specified device.
WdfPdoInitAddCompatibleID The WdfPdoInitAddCompatibleID method adds a compatible ID to the list of compatible IDs for a child device.
WdfPdoInitAddDeviceText The WdfPdoInitAddDeviceText method adds a device description and device location to a device, for a specified locale.
WdfPdoInitAddHardwareID The WdfPdoInitAddHardwareID method adds a hardware ID to the list of hardware IDs for a child device.
WdfPdoInitAllocate The WdfPdoInitAllocate method allocates a WDFDEVICE_INIT structure for a framework-based bus driver, which the bus driver uses when reporting a new device.
WdfPdoInitAllowForwardingRequestToParent The WdfPdoInitAllowForwardingRequestToParent method enables a driver's ability to call WdfRequestForwardToParentDeviceIoQueue.
WdfPdoInitAssignContainerID The WdfPdoInitAssignContainerID method updates the container ID for a child device.
WdfPdoInitAssignDeviceID The WdfPdoInitAssignDeviceID method updates the device ID for a child device.
WdfPdoInitAssignInstanceID The WdfPdoInitAssignInstanceID method updates the instance ID for a child device.
WdfPdoInitAssignRawDevice The WdfPdoInitAssignRawDevice method indicates that the calling driver can support a specified device in raw mode.
WdfPdoInitRemovePowerDependencyOnParent Learn more about: WdfPdoInitRemovePowerDependencyOnParent
WdfPdoInitSetDefaultLocale The WdfPdoInitSetDefaultLocale method sets a device's default locale.
WdfPdoInitSetEventCallbacks The WdfPdoInitSetEventCallbacks method registers a bus driver's event callback functions.
WdfPdoMarkMissing The WdfPdoMarkMissing method informs the framework that a device is no longer accessible.
WdfPdoRemoveEjectionRelationsPhysicalDevice The WdfPdoRemoveEjectionRelationsPhysicalDevice method removes a specified device from the list of devices that must be ejected when another specified device is ejected.
WdfPdoRequestEject The WdfPdoRequestEject method informs the framework that a specified device is about to be ejected from its docking station.
WdfPdoRetrieveAddressDescription The WdfPdoRetrieveAddressDescription method retrieves the address description that is associated with a specified framework device object.
WdfPdoRetrieveIdentificationDescription The WdfPdoRetrieveIdentificationDescription method retrieves the identification description that is associated with a specified framework device object.
WdfPdoUpdateAddressDescription The WdfPdoUpdateAddressDescription method updates the address description that is associated with a specified framework device object.

Callback functions

EVT_WDF_DEVICE_DISABLE_WAKE_AT_BUS A bus driver's EvtDeviceDisableWakeAtBus event callback function performs bus-level operations that disable the ability of one of the bus's devices to trigger a wake-up signal on the bus.
EVT_WDF_DEVICE_EJECT A driver's EvtDeviceEject event callback function handles operations that are necessary to eject a device from its docking station.
EVT_WDF_DEVICE_ENABLE_WAKE_AT_BUS A bus driver's EvtDeviceEnableWakeAtBus event callback function performs bus-level operations that enable one of the bus's devices to trigger a wake-up signal on the bus.
EVT_WDF_DEVICE_REPORTED_MISSING A bus driver's EvtDeviceReportedMissing event callback function informs the driver that the framework has reported the physical device object (PDO) missing to the Plug and Play manager.
EVT_WDF_DEVICE_RESOURCE_REQUIREMENTS_QUERY A bus driver's EvtDeviceResourceRequirementsQuery event callback function creates a resource requirements list that represents the device's required hardware resources.
EVT_WDF_DEVICE_RESOURCES_QUERY A bus driver's EvtDeviceResourcesQuery event callback function creates a resource list that represents a specified device's boot configuration.
EVT_WDF_DEVICE_SET_LOCK A driver's EvtDeviceSetLock event callback function locks the specified device so that it cannot be ejected, or unlocks the device so that it can be ejected.

Structures

WDF_PDO_EVENT_CALLBACKS The WDF_PDO_EVENT_CALLBACKS structure is the dispatch table for a bus driver's event callback functions.
