Thanks that worked out very well, and here is the code:

int fd = 0;
fd = open("/dev/acd0c", O_RDONLY);

while(1)
    {
    success = ioctl(fd, CDIOREADTOCHEADER, &ith);
    if (success != -1)
       {
       close(fd);
       execl("/home/user/test.py", 0);
       }
    else
       {
       close (fd);
       sleep(2); // try again.
       fd = open("/dev/acd0c", O_RDONLY);
       }
  }
