The standard says always to use (off * width, whence) but that is just the external effect if buffering is transparent. __computed_off compensates for the file pointer being necessarily different from gptr(), pptr(). (You can't seek for every putc!) Don't mean to be impatient, just trying to follow along the discussion⦠-- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45628
