19 * ---- rpcss_main.c:
20 * Initialize and start serving requests. Bail if rpcss already is
21 * running.
22 *
23 * ---- RPCSS.EXE:
24 *
25 * Wine needs a server whose role is somewhat like that
26 * of rpcss.exe in windows. This is not a clone of
27 * windows rpcss at all. It has been given the same name, however,
28 * to provide for the possibility that at some point in the future,
29 * it may become interface compatible with the "real" rpcss.exe on
30 * Windows.
31 *
32 * ---- KNOWN BUGS / TODO:
33 *
34 * o Service hooks are unimplemented (if you bother to implement
35 * these, also implement net.exe, at least for "net start" and
36 * "net stop" (should be pretty easy I guess, assuming the rest
37 * of the services API infrastructure works.
38 *
39 * o There is a looming problem regarding listening on privileged
40 * ports. We will need to be able to coexist with SAMBA, and be able
41 * to function without running winelib code as root. This may
42 * take some doing, including significant reconceptualization of the
43 * role of rpcss.exe in wine.
