/* NB: MS-RDPESP's recommendation:
|
|
*
|
|
* <2> Section 3.2.5.1.6: Windows Implementations use IOCTL constants
|
|
* for IoControlCode values. The content and values of the IOCTLs are
|
|
* opaque to the protocol. On the server side, the data contained in
|
|
* an IOCTL is simply packaged and sent to the client side. For
|
|
* maximum compatibility between the different versions of the Windows
|
|
* operating system, the client implementation only singles out
|
|
* critical IOCTLs and invokes the applicable Win32 port API. The
|
|
* other IOCTLS are passed directly to the client-side driver, and the
|
|
* processing of this value depends on the drivers installed on the
|
|
* client side. The values and parameters for these IOCTLS can be
|
|
* found in [MSFT-W2KDDK] Volume 2, Part 2—Serial and Parallel
|
|
* Drivers, and in [MSDN-PORTS].
