* ---- rpcss_main.c:
* Initialize and start serving requests. Bail if rpcss already is
* running.
*
* ---- RPCSS.EXE:
*
* Wine needs a server whose role is somewhat like that
* of rpcss.exe in windows. This is not a clone of
* windows rpcss at all. It has been given the same name, however,
* to provide for the possibility that at some point in the future,
* it may become interface compatible with the "real" rpcss.exe on
* Windows.
*
* ---- KNOWN BUGS / TODO:
*
* o Service hooks are unimplemented (if you bother to implement
* these, also implement net.exe, at least for "net start" and
* "net stop" (should be pretty easy I guess, assuming the rest
* of the services API infrastructure works.
*
* o Is supposed to use RPC, not random kludges, to map endpoints.
*
* o Probably name services should be implemented here as well.
*
* o Wine's named pipes (in general) may not interoperate with those of
* Windows yet (?)
*
* o There is a looming problem regarding listening on privileged
* ports. We will need to be able to coexist with SAMBA, and be able
* to function without running winelib code as root. This may
* take some doing, including significant reconceptualization of the
* role of rpcss.exe in wine.
*
* o Who knows? Whatever rpcss does, we ought to at
* least think about doing... but what /does/ it do?
