Module Name:

    ReplBind.c

Abstract:

    Routines which use RPC to bind and unbind the client to the replicator
    service.

Author:

    John Rogers (JohnRo) 16-Jan-1992

Environment:

    User Mode -Win32

Revision History:

    16-Jan-1992 JohnRo
        Created the repl service RPC stuff from Rita's workstation RPC stuff.
        I'm just going to use identify handles if possible.
    23-Jan-1992 JohnRo
        Correct calls to NetpBindRpc.
    27-Jan-1992 JohnRo
        Changed to use LPTSTR etc.
    30-Jan-1992 JohnRo
        Made changes suggested by PC-LINT.
    05-Feb-1992 JohnRo
        Changes required by new RPC.
    08-Apr-1992 JohnRo
        Fixed UNICODE handling.
    08-Aug-1992 JohnRo
        RAID 2252 (old 9963): repl should prevent export on Windows/NT.
    16-Dec-1992 JohnRo
        Made changes suggested by PC-LINT 5.0
        Added some IN and OUT keywords.
    30-Apr-1993 JohnRo
        Use NetpKdPrint() where possible.
        Use PREFIX_ equates.

Routine Description:

Arguments:

        to bind with.

Return Value:

    The binding handle is returned to the stub routine.  If the bind is
    unsuccessful, a NULL will be returned.
