NAME
     swab - swap bytes

SYNOPSIS
     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.  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.
