There is a lot to deal with here because: % grep ::set_close_on_exec *.cc fhandler.cc:fhandler_base::set_close_on_exec (bool val) fhandler_console.cc:fhandler_console::set_close_on_exec (bool val) fhandler_console.cc: fhandler_base::set_close_on_exec (val); fhandler_socket.cc:fhandler_socket::set_close_on_exec (bool val) fhandler_socket.cc: fhandler_base::set_close_on_exec (val); fhandler_tape.cc:fhandler_dev_tape::set_close_on_exec (bool val) fhandler_tape.cc: fhandler_dev_raw::set_close_on_exec (val); fhandler_tty.cc:fhandler_tty_common::set_close_on_exec (bool val) fhandler_windows.cc:fhandler_windows::set_close_on_exec (bool val) fhandler_windows.cc: fhandler_base::set_close_on_exec (val); and even more importantly: % grep '^fhandler[a-z_0-9]*::dup' *.cc fhandler.cc:fhandler_base::dup (fhandler_base *child) fhandler_clipboard.cc:fhandler_dev_clipboard::dup (fhandler_base * child) fhandler_console.cc:fhandler_console::dup (fhandler_base *child) fhandler_dsp.cc:fhandler_dev_dsp::dup (fhandler_base * child) fhandler_fifo.cc:fhandler_fifo::dup (fhandler_base *child) fhandler_floppy.cc:fhandler_dev_floppy::dup (fhandler_base *child) fhandler_mem.cc:fhandler_dev_mem::dup (fhandler_base *child) fhandler_random.cc:fhandler_dev_random::dup (fhandler_base *child) fhandler_raw.cc:fhandler_dev_raw::dup (fhandler_base *child) fhandler_registry.cc:fhandler_registry::dup (fhandler_base *child) fhandler_serial.cc:fhandler_serial::dup (fhandler_base *child) fhandler_socket.cc:fhandler_socket::dup (fhandler_base *child) fhandler_tape.cc:fhandler_dev_tape::dup (fhandler_base *child) fhandler_tty.cc:fhandler_tty_slave::dup (fhandler_base *child) fhandler_tty.cc:fhandler_pty_master::dup (fhandler_base *child) fhandler_virtual.cc:fhandler_virtual::dup (fhandler_base * child) pipe.cc:fhandler_pipe::dup (fhandler_base *child) I was thinking about a way of collapsing most of those into one generic call. But not for 1.7.1, obviously. cgf -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
