Notifications when process is killed

[Andrea Di Mario]

You won't be able to catch SIGTERM, as Thomas said, but if you need to

know what caused a process to end, the best way is to have code in the
parent process to catch SIGCHLD. When the child ends, for any reason,
its parent is sent SIGCHLD with some parameters, including the signal
number that caused the termination; you can then log anything you
want.

Hi, i understand, i've read that SIGKILL can't catch, but nothing
about SIGTERM.
If i use SIGCHLD, i will have difficult when parent receive a SIGTERM, or not?

Thanks, regards.
