Module Name:

    StrArray.h

Abstract:

    This is the a header file of handy functions and macros for TCHAR
    string arrays.

    These arrays are in the following format (spaces added for clarity):

       one \0 two \0 three \0 \0

    where \0 is a null character in the appropriate format.

    These functions are useful for the NetServerDiskEnum and NetConfigGetAll
    APIs, and possibly others.

Author:

    John Rogers (JohnRo) 03-Jan-1992

Environment:

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

Revision History:

    03-Jan-1992 JohnRo
        Created this file from bits and pieces in RxCommon and NetLib.
    01-Sep-1992 JohnRo
        RAID 5016: NetConfigGetAll heap trash.
