16 The swab() function shall copy nbytes bytes, which are pointed to by
17 src, to the object pointed to by dest, exchanging adjacent bytes. The
18 nbytes argument should be even. If nbytes is odd, swab() copies and
19 exchanges nbytes-1 bytes and the disposition of the last byte is
20 unspecified. If copying takes place between objects that overlap, the
21 behavior is undefined. If nbytes is negative, swab() does nothing.
