Authors: Greg Turner <gmturner007@ameritech.net>, Ove Kaaven <ovek@transgaming.com>
- preliminary implementation of endpoint-mapping via a new on-demand server-ish process - more header fixups - (re)implement RpcEpRegisterA, RpcEpUnregister, and RpcEpResolveBinding using the new rpcss functionality - update the todo list in rpcrt4_main.c a bit - many beautifications and touch-ups - command-line configurable timeout - micro-client imbedded in np_server.c

* ---- 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,

* 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 priveleged
|
||||
* ports. We will need to be able to coexist with SAMBA, and 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?
