The source code for fseek looks a bit dubious here at line 64:
>
> 64 if (iop->_flag & _IOREAD) {
> 65 if (ptrname == 1 && iop->_base && !(iop->_flag&_IONBF)) {
> 66 offset -= iop->_cnt;
> 67 }
> 68 } else if (iop->_flag & (_IOWRT | _IORW)) {
> 69 if (_fflush_u(iop) == EOF) {
> 70 FUNLOCKFILE(lk);
> 71 return (-1);
> 72 }
> 73 }
