*restrict src, void *restrict dst,
swab() copies len bytes from the location referenced by src to the location referenced by dst, swapping adjacent bytes.
If len is zero or less,
swab does nothing. If it is odd, what
happens to the last byte is unspecified. If
dst overlap, behaviour is undefined.
swabfunction is compliant with the X/Open System Interfaces option of the IEEE Std 1003.1-2008 (“POSIX.1”) specification.
swab() function first appeared in Version 7 AT&T UNIX.
