/*
  memcpy(dst, src, len)
  moves len bytes from src to dst.  The result is dst.	This is not
  the same as strncpy or strnmov, while move a maximum of len bytes
  and stop early if they hit a NUL character.  This moves len bytes
  exactly, no more, no less.  See also bcopy() and bmove() which do
  not return a value but otherwise do the same job.
