      NAME
           swab - swap bytes

      SYNTAX
           void swab (from, to, nbytes)
           char *from, *to;
           int nbytes;

      DESCRIPTION
           Swab copies nbytes bytes pointed to by from to the array
           pointed to by to, exchanging adjacent even and odd bytes.
           It is useful for carrying binary data between PDP-11s and
           other machines.  Nbytes should be even and non-negative.  If
           nbytes is odd and positive swab uses nbytes-1 instead. If
           nbytes is negative swab does nothing.
