+/*++
+
+Routine Description:
+
+    Called by the framework as soon as it receives a Device I/O request.
+
+    Note that this callback may run concurrently to the read and write
+    queues' callbacks. This is acceptable in the context of this sample,
+    because the companion application runs Read/Write requests and IOCTL
+    requests sequentially, but your project might require some form of
+    synchronization.
+
+Arguments:
+
+    Queue              - Handle to the IOCTL Queue
+    Request            - Handle to the IOCTL request
+    OutputBufferLength - Length of request's output buffer
+    InputBufferLength  - Length of request's input buffer
+    IoControlCode      - The IOCTL associated with the request
+
+Return Value:
