On failure an explanation will be printed to stderr, obtained from the ex- plain_kill(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

On failure an explanation will be printed to stderr, obtained from the ex- plain_kill(3) function, but still returns to the caller. pid The pid, exactly as to be passed to the kill(2) system call. sig The sig, exactly as to be passed to the kill(2) system call. RETURN VALUE The explain_kill_or_die function only returns on success, see kill(2) for more information. On failure, prints an explanation and exits, it does not return. The explain_kill_on_error function always returns the value return by the wrapped kill(2) system call.
