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.
