WdfDeviceInitSetIoInCallerContextCallback function (wdfdevice.h)

[Applies to KMDF only]

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

Syntax

 [in] PWDFDEVICE_INIT DeviceInit,
 [in] PFN_WDF_IO_IN_CALLER_CONTEXT EvtIoInCallerContext
);

Parameters

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.

 DeviceInit, 
 MyEvtIoInCallerContext
 );
