The Windows implementation shouldn't map file-descriptor values 0, 1, and 2 to the process standard handles. fileno(stdout) may not even be 1 in some cases. It should use `handle = _get_osfhandle(fd)`, which is more generally correct and not limited to hard-coded defaults. Regarding this issue, the docs should clarify that the Windows console's input buffer cannot be used to get the screen buffer size. Typically the input buffer is STDIN_FILENO (0) or opened via "CONIN$" or "CON" (read mode). Thus there is no point to checking stdin in Windows since it will always fail. I agree that the default behavior should be extended to check a platform-dependent tty/console device. In Windows this is `fd = _open("CONOUT$", _O_RDWR)`. ---------- nosy: +eryksun _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue14841> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
