EvtIoInCallerContext [in]A pointer to the driver's EvtIoInCallerContext callback function.
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.
The following code example registers a driver's EvtIoInCallerContext event callback function.
