Write a program where the parent forks o one child, have child send SIGUSR1 to parent, have parent send SIGUSR2 to child. Register (using either signal or sigaction) handlers which will print which sigs were received (for both parent and child). Then have parent terminate child by sending SIGTERM. Wait (wait system call) on status and then report child terminated and its status. (Recall when terminated by a signal, byte 0 of the returned status contains the signal number, is this the case here?)
