Module Name:

    Config.h

Abstract:

    This header file defines the function prototypes of the temporary
    helper routines to get configuration information from the NT
    configuration files.

Author:

    Rita Wong (ritaw) 22-May-1991

Environment:

    Only runs under NT.

Notes:

    You must include the following before this file:

            windef.h OR windows.h  // Win32 type definitions
