unfortunately,  i  haven't  any  linux  boxes  with floppies around to
check,  so  could  somebody    run    this   program on linux  with or
without  media  in  drive  and  (if  possible) with media of different
sizes,  i.e.  1.44M  and 720K floppies, and report what it prints when
run as './floppy 0' or './floppy 1000' or './floppy 1024' ?

#include <stdio.h>
#include <fcntl.h>
#include <errno.h>

int main (int argc, char** argv)
{
  off_t rv;
  off_t offset = ( argc > 1 ? atoi (argv[1]) : 0 );
  int fd = open ( "/dev/fd0", O_RDONLY );
  if ( fd >= 0 )
    {
      rv = lseek ( fd, offset, SEEK_END );
      printf ( "offset = %ld; filepos = %ld\n", offset, rv );
      if ( rv < 0 ) perror ( "lseek" );
    }
  else perror ( "open" );
}
