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.
