loses its controlling terminal. The SIGINT signal is sent when the
user at the controlling terminal presses the interrupt character,
which by default is ^C (Control-C). The SIGQUIT signal is sent when
the user at the controlling terminal presses the quit character, which
by default is ^\ (Control-Backslash). In general you can cause a
program to simply exit by pressing ^C, and you can cause it to exit
with a stack dump by pressing ^\.
