Abstract:

    This file contains NetrReplGetInfo().

Author:

    John Rogers (JohnRo) 20-Jan-1992

Environment:

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

Revision History:

    20-Jan-1992 JohnRo
        Created.
    24-Jan-1992 JohnRo
        Changed to use LPTSTR etc.
        P_ globals are now called ReplGlobal variables in replgbl.h.
        Moved some code from here to ReplConfigAllocAndBuildApiRecord().
        This routine can use a shared lock for the config data.
    31-Jan-1992 JohnRo
        Fixed an error code.
    24-Mar-1992 JohnRo
        Renamed many ReplGlobal vars to ReplConfig vars.
    13-Jan-1993 JohnRo
        Made some changes suggested by PC-LINT 5.0
