21 The swab() function copies nbytes bytes, which are pointed to by src,
22 to the object pointed to by dest, exchanging adjacent bytes. The
23 nbytes argument should be even. If nbytes is odd swab() copies and
24 exchanges nbytes−1 bytes and the disposition of the last byte is
25 unspecified. If copying takes place between objects that overlap, the
26 behavior is undefined. If nbytes is negative, swab() does nothing.
