10 History:
11 24 May 2008 - Created
12 2 July 2008 - Added device names as seen from user-mode
13 5 July 2008 - Added macros for checking device type
14 14 Feb 2009 - Added base control codes for nonstandard extensions
15
16 This file contains definitions and structures for Windows NT4 style
17 multimedia drivers. The NT4 DDK has these split across multiple header
18 files: NTDDSND.H, NTDDWAVE.H, NTDDMIDI.H, NTDDMIX.H and NTDDAUX.H
19
20 Should you have an unstoppable urge to build an NT4 multimedia driver
21 against these headers, just create the other files listed above and make
22 them #include this one.
23
24 There are also a number of additional enhancements within this file
25 not found in the originals (such as DOS device name strings and device
26 type IDs).
