I stumbled about this 2007 post which summarises very nicely all the pitfalls and minefields with stdin/stdout on different platforms: http://lists.trolltech.com/qt-interest/2007-07/msg00841.html A longer, but very informative post. And I think most of it is still valid as of today, when I compare it with my most recent own experience with QFile on stdin. ;) I like this quote here: "What surprises me the most is that a filter is a one of the most simple UI design patterns. How come this is all so complicated? Or did I go wrong somewhere on the way?" Apparently a never-ending story, given the amount of people (according to Google) that try to do asynchronous IPC with Qt and stdin/out - and finally give up ;) Cheers, Oliver _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
