Question

Which library function uses kill to send any signal to the current process?

Answer 1

Answer:

Of course, you can use raise() to send any signals. For example, sending SIGQUIT terminates the program and generates a core dump; sending SIGINT is equivalent to hitting Ctrl-C; sending SIGTERM or SIGKILL kills the program. We use SIGUSR1 here because it illustrates a way of using user-defined signals.
