I am sorry for my late reply,
and thank for your suggestion.
I did't know functions such as
"getpid()","kill()".

Well, I tried and realized...
If you use "kill(getpid(),SIGINT)",
it works. (ie. callback ok!)
Instead,if you send "Control-C" by keyboard input,
it does not. (nothing happens,signal ignored)

It is confusing.
