    ConfClos.c

Abstract:

    This module contains NetpCloseConfigData.  This is one of the new net
    config helpers.

Author:

    John Rogers (JohnRo) 26-Nov-1991

Environment:

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

Revision History:

    26-Nov-1991 JohnRo
        Created this routine, to prepare for revised config handlers.
    11-Feb-1992 JohnRo
        Added support for using the real Win32 registry.
        Added support for FAKE_PER_PROCESS_RW_CONFIG handling.

    This function closes the system configuration file.

    WARNING: Closing the same config handle twice can be nasty.  There

    ConfigHandle - Is the handle returned from NetpOpenConfigData().

Return Value:

    NET_API_STATUS - NERR_Success or reason for failure.
