/*
* COPYRIGHT: See COPYING in the top level directory
* PROJECT: ReactOS NDIS library
* FILE: ndis/config.c
* PURPOSE: NDIS Configuration Services
* PROGRAMMERS: Vizzini (vizzini@plasmic.com)
* REVISIONS:
* Vizzini 07-28-2003 Created
* NOTES:
* - Resource tracking has to be implemented here because of the design of the NDIS API.
* Whenever a read operation is performed, the NDIS library allocates space and returns
* it. A linked list is kept associated with every handle of the memory allocated to
* it. When the handle is closed, the resources are systematically released.
* - The NDIS_HANDLE Configuraiton context is no longer a registry handle. An opaque struct
* had to be created to allow for resource tracking. This means that Miniports cannot just
* pass this NDIS_HANDLE to things like ZwQueryValueKey(). I don't thknk they do (they
* certainly should not), but it should be kept in mind.
* - I have tried to stick to the DDK's definition of what return values are possible, which
* has resulted in stupid return values in some cases. I do use STATUS_RESOURCES in a few
* places that the DDK doesn't explicitly mention it, though.
* - There's a general reliance on the fact that UNICODE_STRING.Length doesn't include a trailing
* 0, which it shouldn't
* - I added support for NdisParameterBinary. It's at the end of the struct. I wonder if
* it'll break things.
* - All the routines in this file are PASSIVE_LEVEL only, and all memory is PagedPool
