(i.e. the converse of cygwin_attach_handle_to_fd(), actually) Well, the simple workaround would be to write a wrapper function for cygwin_attach_handle_to_fd; the wrapper would call DuplicateHandle to get a spare copy of the original handle and then pass that duplicated handle to cygwin_attach_handle_to_fd instead of the original handle; that way, when you close the fd, the duplicate of the handle is closed, entirely independently of the original. cheers, DaveK -- Can't think of a witty .sigline today.... -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
