Ending an application

[cmusik]

I have played a bit with ex_ncurses, but have not found how to exit properly ncurses mode:

ExNcurses.n_begin()
ExNcurses.noecho()
IO.puts(inspect(ExNcurses.getch()))
ExNcurses.n_end()

I would have expected that after pressing any key, the application would end. What am I'm missing?

Versions:
ex_ncurses 0.3.1
elixir 1.15.0
