Is the structure large?
If < 4KB - then no needs in these perversions, just copy it to
Irp->AssociatedIrp.SystemBuffer.

will be applied upon an IOCTL call. The users application will need to be able
to access/modify this structure. Is there a way I can map the kernel space
containing the structure into user space so that the application can
access/modify it directly? Thank you for your time.
