Replacing (Ctrl-C) signal with (Ctrl-D)

I want to have my program ignore the (Ctrl-C) signal and instead should terminate on (Ctrl-D).
How can i do that?

Ctrl-C is usually SIGINT, so all you need to ignore it. :)

Code:

---

struct sigaction sac;

if (sigaction(SIGINT, NULL, &sac) == -1)
        perror("Couldn't get old handler");
else {
        sac.sa_handler = SIG_IGN;
        if (sigaction(SIGINT, &sac, NULL) == -1)
                perror("Couldn't ignore SIGINT");
}

---

And ctrl-D generates EOF on the input stream.
Aren't you glad you learnt how to use fgets :)

Code:

---

while ( fgets( buff, sizeof buff, stdin ) != NULL ) {
    // do stuff
}
if ( feof(stdin) ) {
    // user pressed ctrl-D
}
