V podstate:
while (1){
      fd = open(device, O_NONBLOCK);
      status = ioctl(fd, CDROM_MEDIA_CHANGED, CDSL_CURRENT);
      if (status)
           neco proved;
      close(fd);
      sleep(nejaky cas);
}
     
Na zjisteni, jestli je CD audio nebo ne staci:

        status = ioctl(fd, CDROM_DISC_STATUS);                           
       if (status == CDS_AUDIO) neco;
else if (status == CDS_DATA_1 || status == CDS_DATA_2) 
   neco jinyho;
Tohle vsechno mi ale bohuzel na 2.0.33 nechodi, nicmene s
novymy kernely v pohode.
