Module Name:

    NetDebug.h

Abstract:

    This header file declares various debug routines for use in the
    networking code.

Author:

    John Rogers (JohnRo) 11-Mar-1991

Environment:

    ifdef'ed for NT, any ANSI C environment, or none of the above (which
    implies nondebug).  The interface is portable (Win/32).
    Requires ANSI C extensions: slash-slash comments, long external names.

Revision History:

    11-Mar-1991 JohnRo
        Created.
    25-Mar-1991 JohnRo
        Added more FORMAT_ strings.  Got rid of tabs in file.
    28-Mar-1991 JohnRo
        Added FORMAT_HEX_ strings.
    08-Apr-1991 JohnRo
        Added temporary versions of wide char stuff (FORMAT_LPTSTR, etc).
    16-Apr-1991 JohnRo
        Added PC-LINT version of NetpAssert(), to avoid occasional constant
        Boolean value messages.  Added wrappers for NT debug code, to avoid
        recompile hits from <nt.h> all over the place.
    25-Apr-1991 JohnRo
        Created procedure version of NetpDbgHexDump().
    13-May-1991 JohnRo
        Added FORMAT_LPVOID to replace FORMAT_POINTER.  Changed nondebug
        definition of NetpDbgHexDump() to avoid evaluating parameters.
    15-May-1991 JohnRo
        FORMAT_HEX_WORD was wrong.
    19-May-1991 JohnRo
        Improve LINT handling of assertions.
    21-May-1991 JohnRo
        Added NetpDbgReasonable() for partial hex dumps.
    13-Jun-1991 JohnRo
        Added NetpDbgDisplay routines.
        Moved DBGSTATIC here from <Rxp.h>.
    02-Jul-1991 JohnRo
        Added display routines for print job, print queue, and print dest.
    05-Jul-1991 JohnRo
        Avoid FORMAT_WORD name (used by MIPS header files).
    22-Jul-1991 JohnRo
        Implement downlevel NetConnectionEnum.
    25-Jul-1991 JohnRo
        Wksta debug support.
    03-Aug-1991 JohnRo
        Rename wksta display routine for consistency.
    20-Aug-1991 JohnRo
        Allow use in nondebug builds.
    20-Aug-1991 JohnRo
        Downlevel NetFile APIs.
    11-Sep-1991 JohnRo
        Downlevel NetService APIs.  Added UNICODE versions of some FORMAT_
        equates.  Added FORMAT_ULONG for NT use.
    13-Sep-1991 JohnRo
        Change "reasonable" debug amount to be an even number of lines.
        Create an equate for it.  Added LPDEBUG_STRING and a FORMAT_ for that.
    15-Oct-1991 JohnRo
        Implement remote NetSession APIs.
    11-Nov-1991 JohnRo
        Implement remote NetWkstaUserEnum().  Added FORMAT_RPC_STATUS.
    26-Dec-1991 JohnRo
        Added stuff for replicator APIs.
    07-Jan-1992 JohnRo
        Added NetpDbgDisplayWStr() for UNICODE strings.
        Added NetpDbgDisplayTStr() to be consistent.
    26-Feb-1992 JohnRo
        Added NetpDbgDisplayTimestamp() (seconds since 1970).
    15-Apr-1992 JohnRo
        Moved FORMAT_ equates into /nt/private/inc/debugfmt.h (so they
        can be used by the service controller as well).
    13-Jun-1992 JohnRo
        RAID 10324: net print vs. UNICODE.
    16-Aug-1992 JohnRo
        RAID 2920: Support UTC timezone in net code.
    24-Aug-1992 JohnRo
        Fixed free build again (misnamed repl import/export display macros).
    02-Oct-1992 JohnRo
        RAID 3556: DosPrintQGetInfo (from downlevel) level=3 rc=124.
        (Added NetpDbgDisplayPrintQArray.)
    05-Jan-1993 JohnRo
        Repl WAN support (get rid of repl name list limits).
        Made changes suggested by PC-LINT 5.0
    04-Mar-1993 JohnRo
        RAID 12237: replicator tree depth exceeded (add display of FILETIME
        and LARGE_INTEGER time).
    31-Mar-1993 JohnRo
        Allow others to display replicator state too.
