That doesn't ever create a backup file or a temporary file. It opens xxx for read, unlinks it, opens xxx for writing, then reads from the original handle and writes to the second handle. This is AFAIUI impossible on windows, but possible on things like unix and VMS (where the unlink is skipped because of the automatic versioning). -- 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/
