no questions when quitting

[Krzysztof Poc]

Hello

How can I force emacs to quit immediately after pressing C-x C-c
without asking any questions.
I would like all remaining modified buffers to be not saved and all
running emacs subprocesses to be killed.

I read in info documentation that confirm-kill-emacs variable adjusts
this behaviour.
Unfortunately I don't know to which value I should set it to achieve
what I want since nil value leads me to yes-or-no-p function.

thanks for help
