Routine Description:
This event handled device control calls.
Arguments:
Queue - Handle of the queue object associated with the request
Request - Handle of the request object
OutputBufferLength - length of the request's output buffer
InputBufferLength - length of the request's input buffer
IoControlCode - the driver-defined or system-defined I/O control code
Return Value:
None
