Are you doing an single process application that produces output on many terminals? ie the program is kind of like a service? gotcha. I want to write a TCP server that handles incoming requests in threads (one thread per request using SocketServer.ThreadingTCPServer). Now, I want the server to use curses for client-server communication (client will be telnet). Thus, my programm runs in a single process (although several threads) and provides several curses screens (one for each client.) I see. At first, here is some relevant source from Modules/_cursesmodule.c : A number of SysV or ncurses functions don't have wrappers yet; if you need a given function, add it and send a patch. Here's a list of currently unsupported functions: addchnstr addchstr chgat color_set define_key del_curterm delscreen dupwin inchnstr inchstr innstr keyok mcprint mvaddchnstr mvaddchstr mvchgat mvcur mvinchnstr mvinchstr mvinnstr mmvwaddchnstr mvwaddchstr mvwchgat mvwgetnstr mvwinchnstr mvwinchstr mvwinnstr newterm resizeterm restartterm ripoffline scr_dump scr_init scr_restore scr_set scrl set_curterm set_term setterm tgetent tgetflag tgetnum tgetstr tgoto timeout tputs vidattr vidputs waddchnstr waddchstr wchgat wcolor_set winchnstr winchstr winnstr wmouse_trafo wscrl So the answer is that, no, you can't use newterm currently. But even if you did, it's not certain that you could use multiterminal ncurses in a multithreaded environment; AFAIK in ncurses you just change the current term and then go on with normal curses calls; is there a current term per thread, or is there one per process? I couldn't find an answer in the short search I did. I am afraid you will have to make it into a 3-tier arch; that is, your server has the data model and absolutely no curses knowledge, and the clients run a middle application, interfacing ncurses I/O and server protocol. -- TZOTZIOY, I speak England very best.

curses for different terminals
Hi all, I want to use curses in a server application that provides a GUI for telnet clients. Therefore, I need the functionality to open and handle several screens. Concerning http://dickey.his.com/ncurses/ncurses-intro.html#init this can be done using the function newterm(type,ofp,ifp). However, this function seems not to be defined in the python library. Does anyone know how this can be done in python? cheers, - harold - -- Life is what happens while you're busy making other plans -- John Lennon -- http://mail.python.org/mailman/listinfo/python-list

Therefore, I need the functionality to open and handle several screens. Just to make sure we understand what you want to do: 1. Are you doing an single process application that produces output on many terminals? ie the program is kind of like a service? 2. Are you doing an application with one session per terminal? ie a user starts your app in every terminal, no multi-term output from a single process. 3. Are you doing an application that runs on one terminal but with many virtual sessions (or screens), kind of like the `screen(1)` program or the behaviour of the linux or Novell console?

Does anyone know how this can be done in python? Select one of the above, or describe more the desired situation if I didn't cover your case, and we will try to help you more. -- TZOTZIOY, I speak England very best.
