Also look at the svcctl.ild definition in SAMBA_4_0.

It's not too hard.  Look at
svn://svnanon.samba.org/samba/SAMBA_3_0/source/utils/net_rpc_service.c

You'll need to do a few things.

* Add request/reply  structures to include/rpc_svcctl.h
* Add the parsing functions to rpc_parse/parse_svcctl
* Add the client function to rpc_client/cli_svcctl.c
* Add in the new command to net_rpc_service.c

Start by looking at how the existing service management
calls are implemented and then start adapting that to the
new call.  All make sure you have a current release of
wireshark to anaylze the traffic and make sure that
parsing functions are doing the right thing.  Might even be
good idea to get comfortable with the trafiic between
two windows servers while playing with the Service Control
MMC plugin.

Hope this helps get you started.
