Routine Description:
This event is called when the framework receives IRP_MJ_DEVICE_CONTROL
requests from the system.
Arguments:
Queue - Handle to the framework queue object that is associated
with the I/O request.
Request - Handle to a framework request object.
OutputBufferLength - length of the request's output buffer,
if an output buffer is available.
InputBufferLength - length of the request's input buffer,
if an input buffer is available.
IoControlCode - the driver-defined or system-defined I/O control code
(IOCTL) that is associated with the request.
