  memcpy(void
    * restrict dst, const
    void * restrict src,
    size_t len);
memcpy() function copies len
  bytes from string src to string
  dst. The arguments must not overlap — behavior if
  the arguments overlap is undefined. To copy byte strings that overlap, use
  memmove(9).
memcpy() function returns the original value of
  dst.
memcpy() function conforms to
  ISO/IEC 9899:1999 (“ISO C99”).
