Hello,
I’m doing test coverage on a daemon. The daemon is tested by a script
that launches it and eventually terminates it with kill(1). However,
the corresponding gcda files are not updated with actual coverage data.
How can gcov be told to flush its coverage data to disk when the program
is killed?
Thanks,
Ludo’.

maybe you can modify slightly your deamon, catch the signal
and do a "clean" exit by calling "exit" in the signal handler
or something?
And have a conditional in your code to include/exclude that
behavior depending if you compile with coverage or not.

If you can catch the signal, call __gcov_flush(). If you can't catch
the signal, you're out of luck. Well, I suppose you could have the
program call __gcov_flush every so often.
