Don't use TCP sockets for local communication. Use QLocalSocket (or AF_UNIX directly). stdin does not differ much from sockets, it is in blocking mode by default (so you don't need to use polling), and can be switched to non-blocking mode. -- Regards, Konstantin _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
