Abstract:

    This file contains support code to convert between old and new server
    info levels.

Author:

    John Rogers (JohnRo) 02-May-1991

Environment:

    Portable to any flat, 32-bit environment.  (Uses Win32 typedefs.)
    Requires ANSI C extensions: slash-slash comments, long external names.

Revision History:

    02-May-1991 JohnRo
        Created.
    09-May-1991 JohnRo
        Made some LINT-suggested changes.
    28-May-1991 JohnRo
        Added incomplete output parm to RxGetServerInfoLevelEquivalent.
    14-Jun-1991 JohnRo
        Correct IncompleteOutput values.
    17-Jul-1991 JohnRo
        Extracted RxpDebug.h from Rxp.h.
    21-Nov-1991 JohnRo
        Removed NT dependencies to reduce recompiles.
    26-Aug-1992 JohnRo
        RAID 4463: NetServerGetInfo(level 3) to downlevel: assert in convert.c.
        Use PREFIX_ equates.
