WdfDeviceInitSetIoInCallerContextCallback function

-description

[Applies to KMDF only]

The WdfDeviceInitSetIoInCallerContextCallback method registers a driver's EvtIoInCallerContext event callback function.

-parameters

-param DeviceInit [in]

A pointer to a WDFDEVICE_INIT structure.

-param EvtIoInCallerContext [in]

A pointer to the driver's EvtIoInCallerContext callback function.

-remarks

If a driver calls WdfDeviceInitSetIoInCallerContextCallback, it must do so before it calls WdfDeviceCreate. For more information about calling WdfDeviceCreate, see Creating a Framework Device Object.

For more information about the EvtIoInCallerContext event callback function, see Intercepting an I/O Request before it is Queued.

Examples

The following code example registers a driver's EvtIoInCallerContext event callback function.

WdfDeviceInitSetIoInCallerContextCallback(
                                          DeviceInit, 
                                          MyEvtIoInCallerContext
                                          );
