g_print()???? That prints data to the stdout (terminal), but not to the
stdin of the sister app (I tried, it didn´t work).

uhm.... I just kill the app called by popen() at the exit call... I guess
that does the same trick:
system(kill -INT a_command); // the app needs a SIGINT, not a SIGKILL
Thanks for the suggestion, though :-) (when first testing the app, I
suddenly realized my ps -aux showed a lot of processes that should be
dead....;-) )
