hi, I have fixed pipe and added dup and dup2 to nt/os module. The results can be seen here: https://github.com/paweljasinski/IronLanguages/tree/tinker-with-file
However, I am not 100% sure, that the way it is now is right. At the moment IP manages its own file descriptors available via nt/os module. On platforms, such mono/linux, it is probably redundant. Perfectly functioning posix layer with native file descriptors exist. I suspect there is a way to access it. On classic windows there is msvcrt which can be used, analog to the way cpython does. As far as I can tell IP targets other windows platforms without msvcrt support and I am not able to access situation there. Any ideas and comments are welcome. --pawel Ref: https://ironpython.codeplex.com/workitem/7267 _______________________________________________ Ironpython-users mailing list Ironpython-users@python.org https://mail.python.org/mailman/listinfo/ironpython-users
