Module Name:

    Disp.c

Abstract:

    This file contains routines which display low-level data items in
    a consistent manner.  The output is done in a fixed-width-column
    fashion, similar to some of the NET.EXE outputs.  These routines are
    part of the RxTest program.

Author:

    John Rogers (JohnRo) 03-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:

    03-May-1991 JohnRo
        Created.
    15-May-1991 JohnRo
        Prevent possible errors in DisplayString if string has % in it.
        Added DisplayWord(), DisplayWordHex().
    13-Jun-1991 JohnRo
        Moved from RxTest to NetLib; changed routine names.
    05-Jul-1991 JohnRo
        Avoid FORMAT_WORD name (used by MIPS header files).
    10-Sep-1991 JohnRo
        Made changes suggested by PC-LINT.  (LmCons.h isn't needed.)
    13-Sep-1991 JohnRo
        Use LPDEBUG_STRING instead of LPTSTR, to avoid UNICODE problems.
    07-Jan-1992 JohnRo
        Added NetpDbgDisplayTStr() and NetpDbgDisplayWStr().
    19-Jul-1992 JohnRo
        RAID 464 (old RAID 10324): net print vs. UNICODE.
    17-Aug-1992 JohnRo
        RAID 2920: Support UTC timezone in net code.
    05-Jan-1993 JohnRo
        Repl WAN support (get rid of repl name list limits).
        Avoid stack overflow on very long strings.
