Module Name:

    ConvPrt.c

Abstract:

    This module contains:

        NetpConvertPrintDestArrayCharSet
        NetpConvertPrintDestCharSet
        NetpConvertPrintJobArrayCharSet
        NetpConvertPrintJobCharSet
        NetpConvertPrintQArrayCharSet
        NetpConvertPrintQCharSet

    This routines may be used for UNICODE-to-ANSI conversion, or
    ANSI-to-UNICODE conversion.  The routines assume the structures are
    in native format for both input and output.

Author:

    John Rogers (JohnRo) 20-Jul-1992

Environment:

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

Notes:

    Beware that many of the parameters to the functions in this file
    are implicitly used by the various COPY_ and CONVERT_ macros:

        IN LPVOID FromInfo
        OUT LPVOID ToInfo
        IN BOOL ToUnicode
        IN OUT LPBYTE * ToStringAreaPtr

Revision History:

    20-Jul-1992 JohnRo
        Created for RAID 10324: net print vs. UNICODE.
    16-Dec-1992 JohnRo
        DosPrint API cleanup.
        Allow use of these routines for setinfo APIs.
        Added NetpConvertPrintQArrayCharSet.
    07-Apr-1993 JohnRo
        RAID 5670: "NET PRINT \\server\share" gives err 124 (bad level) on NT.
    14-Apr-1993 JohnRo
        RAID 6167: avoid access violation or assert with WFW print server.
