WdfDeviceInitSetIoInCallerContextCallback method

[Applies to KMDF only]

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

Syntax


VOID WdfDeviceInitSetIoInCallerContextCallback(
  [in]  PWDFDEVICE_INIT DeviceInit,
  [in]  PFN_WDF_IO_IN_CALLER_CONTEXT EvtIoInCallerContext
);

Parameters

DeviceInit [in]

A pointer to a WDFDEVICE_INIT structure.

EvtIoInCallerContext [in]

A pointer to the driver's EvtIoInCallerContext callback function.

Return value

None

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
                                          );
