If something raises it with kill(). Note that SIGTERM is the default
signal sent by the kill and killall commands.

Correct. SIGTERM isn't sent synchronously (i.e. in response to the
actions of the process which receives it).

Install a signal handler using sigaction() with the SA_SIGINFO flag;
the sending process ID will be in the si_pid field of the siginfo_t
structure. Other fields of that structure may also contain useful
information.
