Thank you!
	BTW,why the function "kill_my_pg(sig)" do a system call "kill(0,sig)" with the first parameter "0"? why not to kill himself only but a whole group?

Consider the ip_down_hook plugin hook if you want to catch either event.
pppd can also be killed with SIGKILL, unhandled, and so kernel destroys
interface.  No code in pppd executed.  No ip_down_hook executed.
