Please, do the following: issue in zeus xterm the command: man signal
and read it.
Then execute the following code (ad-hoc from the top of my head):
#include <signal.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
typedef void (*sighandler_t)(int);
sighandler_t signal_handler;
sighandler_t signal(int signum, sighandler_t handler);
int main() {
signal_handler = signal(SIGINT, SIG_DFL);
printf ("Old signal handler is 0x%x\n", signal_handler);
}
Where the following is also known:
#define SIG_ERR ((__sighandler_t) -1) /* Error return. */
#define SIG_DFL ((__sighandler_t) 0) /* Default action. */
#define SIG_IGN ((__sighandler_t) 1) /* Ignore signal. */
This program serves the double purpose:
[1] Gives you the address of the old SIGINT handler which was executed
prior execution of this code;
[2] After execution, repeat the routine (ping) and see if <ctrl c>
terminates the ping process.
All other comments are obvious (testing the Zeus SIGINT signal, yada
yada yada... ;-)
