                     12: The  ordering of  bytes  within a  word differs  from machine  to
                     13: machine.  This may cause problems when moving binary data between
                     14: machines.  swab interchanges each  pair of bytes in the array src
                     15: that is n bytes long, and  places the result into the array dest.
                     16: The length nb should be an even number, or the last byte will not
                     17: be touched.  src and dest may be the same place.

                     21: This example  prompts for an integer; it  then prints the integer
                     22: both as you entered it, and as it appears with its bytes swapped.
