What Does This Do?

[Question]

Could some1 tell me what this program exactly does? Iv compiled and run it but cant seem to work out what exactly it does


#include <signalh>
#include <stdio.h>
#include <unistd.h>

void ouch(int sig)
{
printf("OUCH! ? I got signal %d\n, sig);
}

main()
{
signal(SIGINT, ouch);
while(1)
{
printf("Hello world\n");
sleep(1);
}
}

Signal usage. Signal descriptions.

Basicly, it waits for an interrupt from the keyboard, and then it calls the function.
