WdfPdoInitSetEventCallbacks method
[Applies to KMDF only]
The WdfPdoInitSetEventCallbacks method registers a bus driver's event callback functions.
Syntax
VOID WdfPdoInitSetEventCallbacks( [in] PWDFDEVICE_INIT DeviceInit, [in] PWDF_PDO_EVENT_CALLBACKS DispatchTable );
Parameters
- DeviceInit [in]
-
A pointer to a WDFDEVICE_INIT structure.
- DispatchTable [in]
-
A pointer to a caller-allocated WDF_PDO_EVENT_CALLBACKS structure.
Return value
None
Remarks
The bus driver must allocate a WDF_PDO_EVENT_CALLBACKS structure and fill in the structure with pointers to the driver's event callback functions.
The driver must call WdfPdoInitSetEventCallbacks before calling WdfDeviceCreate. For more information about calling WdfPdoInitSetEventCallbacks and WdfDeviceCreate, see Creating Device Objects in a Bus Driver.
Examples
The following code example initializes a WDF_PDO_EVENT_CALLBACKS structure and then calls WdfPdoInitSetEventCallbacks.
PWDFDEVICE_INIT pDeviceInit = NULL;
WDF_PDO_EVENT_CALLBACKS pdoCallbacks;
pDeviceInit = WdfPdoInitAllocate(Device);
WDF_PDO_EVENT_CALLBACKS_INIT(&pdoCallbacks);
pdoCallbacks.EvtDeviceResourceRequirementsQuery = Bus_Pdo_EvtDeviceResourceRequirementsQuery;
WdfPdoInitSetEventCallbacks(
pDeviceInit,
&pdoCallbacks
);
