38 Aside from the SIGIOT
, I know of only one bug
, a real strange one
:
39 I wrote a utimes interface
, which copies elements from timevals
40 to utimbufs
. This code is known good
. The problem is that in
41 emacs
, the utime doesn
't seem to take effect (i.e. doesn't change the
42 dates at all
) unless I call report_file_error
*after
* the utime returns
!
44 if (utime (name
, &utb
) < 0)
48 /* For some reason, if this is taken out, then the utime above breaks! */
49 /* (i.e. it doesn't set the time. This just makes no sense... */
50 /* Eric - May 4, 1987 */
51 report_file_error ("Worked just find\n", Qnil
);
53 Without any sort of debugger that works on
emacs (I know
... but I dont have
54 *time
* right now to start with gdb
), it was quite time consuming to track
57 But since
this code is only used
for an optional
4th argument to one command
58 (copy
-file
), it would say that it is non
-critical
