Ignoring Unix signals

Here is the interesting small C program I came across to ignore the unix signals!. Basically I'm a Java programmer, so this small C impressed me a lot :)

Below program ignores the CTRL + C signal,

test.c

#include < stdio.h >
#include < signal.h >


main()
{
signal(SIGINT,SIG_IGN);
while(1)
printf("You can't kill me with SIGINT anymore, dude\n");
return 0;
}


gcc test.c -o testout
./testout

Running the above program completely ignores the CRTL + C command and keep on running with out aborting. CRTL + C sends the SIGINT signal and we ignore that in program.
