How to use pcap_breakloop?

Question

I have a pcap_loop function in another function, that captures packets until the user stops it, i.e.

void functionA()
{
   signal(SIGINT, terminate_process);         


        

Answer 1

You can use alarm to generate a signal after a given number of seconds:

void functionA()
{
    signal(SIGALRM, terminate_process); 
    alarm(100);
}
