While technically correct, this is bogus. We have a variable ret, but
we don't return it. And we have a variable dst, but we don't use it as
destination pointer.

Please change the
	*ret++ = *((char *)src);
into
	*dst++ = *((char *)src);
and leave all the rest.

Best regards,

On my planet, to rest is to rest -- to cease using energy. To me,  it
is  quite  illogical to run up and down on green grass, using energy,
instead of saving it.
