Right, mkstemp gives you a file name that you can then safely open. In
code where I didn't want to break the existing flow, I've used the
following pattern many times:
fd = mkstemp(filename);
if (fd < 0) {
perror("mkstemp");
return NULL;
}
close(fd);
/* Go on to use filename as the name of the temporary file... */
It's an extra few system calls, but usually it doesn't matter.
Thanks for this additional hint. Actually I've thought about
this option and it is a good hint that it is not unusual. But
as I said in my previous mail, at this place I need to open an
existing file and we do not need a random filename here.
Kind regards
Andreas.
