/*
    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).
