/*
ReactOS Sound System
NT4 Multimedia Audio Support (ntddsnd.h)
This file is in the public domain.
Author:
Andrew Greenwood (andrew.greenwood@silverblade.co.uk)
History:
24 May 2008 - Created
2 July 2008 - Added device names as seen from user-mode
5 July 2008 - Added macros for checking device type
14 Feb 2009 - Added base control codes for nonstandard extensions
This file contains definitions and structures for Windows NT4 style
multimedia drivers. The NT4 DDK has these split across multiple header
files: NTDDSND.H, NTDDWAVE.H, NTDDMIDI.H, NTDDMIX.H and NTDDAUX.H
Should you have an unstoppable urge to build an NT4 multimedia driver
against these headers, just create the other files listed above and make
them #include this one.
There are also a number of additional enhancements within this file
not found in the originals (such as DOS device name strings and device
type IDs).
