Hi, 

I made some modifications to your source code and now it works well.
Here it is:

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

void terminate(int a);

void ctrlbrk(void (*fptr)(int))
{
  signal (SIGINT, fptr);
}

void terminate(int a)
{
  puts("I am doing clean up and exiting because you hit Contro-C");
  exit (0);
}

int main()
{
  ctrlbrk(terminate); // when ^c is hit call the cleanup funtion
  while (1)
  puts("I am running on and on and on and on!");
}

Timo
