|
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).
