Module Name:
    master.h

Abstract:
    Constants and some global data definition.

Author:
    Ported from Lan Man 2.x

Environment:
    Contains NT-specific code.
    Requires ANSI C extensions: slash-slash comments, long external names.

Revision History:
    10/07/91    (madana)
        ported to NT. Converted to NT style.
    19-Dec-1991 JohnRo
        Deleted unused (and incorrect) MAX_SHARE equate.
    26-Dec-1991 JohnRo
        Added equate for unguarded value of master_list_rec.grd_count.
    20-Jan-1992 JohnRo
        More changes suggested by PC-LINT.
        Added global flag for ReplTest use.
        Changed to use NetLock.h (allow shared locks, for one thing).
        Added lockcount and time_of_first_lock fields.
        Added RMGlobalMasterListHeader (was master_list_header) and
        RMGlobalMasterListCount.
    24-Jan-1992 JohnRo
        Changed to use LPTSTR etc.
    10-Feb-1992 JohnRo
        Added lock for master's client list (RMGlobalClientList).
    24-Mar-1992 JohnRo
        Renamed many ReplGlobal vars to ReplConfig vars.
    25-Oct_1992 jimkel
        renamed RMGlobalClient* to RMGlobalImport*
        removed RMGlobalClientListLock now using ReplConfigLock
    05-Jan-1993 JohnRo
        Repl WAN support (get rid of repl name list limits).
    04-Mar-1993 JohnRo
        RAID 7988: downlevel repl importer might not see lock file
        for new first-level dir.
