so this is my current code how do i implement this to the code : Before calling sigaction$(),$ you should first use sigemptyset$()$ to empty the signal set. $($Use $\text{'}$$ man

sigemptyset' to find out the details.$).$ Modify your test$\_$signal.cpp program above by using sigaction $()$ to

intercept SIGINT; replace the "for" loop with "while $(1)$; you should be able to quit the program by

entering $"^\backslash ".($Need to intercept SIGQUIT.$).$ here is my code : $//$test$\_$alarm.cpp

#include

#include

#include

using namespace std;

$//$simulates an alarm clock

void alarm$\_$off$($int sig$)$

$\{$

cout $<<$ "Alarm has gone off $"<<$ endl;

$\}$

$//$tell child process to wait for $5$ seconds before sending

$//$a SIGALRM signal to its parent.

int main$()$

$\{$

int pid;

cout $<<$ "Alarm testing!" $<<$ endl;

if $(($pid $=$ fork$())==0)\{//$child

sleep $(5)$;

$/*$

Get parent process id$,$ send SIGALARM signal to it$.$

$*/$

kill $($getppid$(),$ SIGALRM$)$;

return $1$;

$\}$

$//$parent process arranges to catch SIGALRM with a call

$//$to signal and then waits for the inevitable.

cout $<<$ "Waiting for alarm to go off!" $<<$ endl;

$($void$)$ signal $($SIGALRM$,$ alarm$\_$off$)$;

pause$()$; $//$process suspended, waiting for signals to wake up

cout $<<$ "Done!" $<<$ endl;

return $1$;

$\}$
