DESCRIPTION

15       The  memcpy() function shall copy n bytes from the object pointed to by
16       s2 into the object pointed to by s1. If  copying  takes  place  between
17       objects that overlap, the behavior is undefined.

RETURN VALUE

20       The  memcpy()  function shall return s1; no return value is reserved to
21       indicate an error.
