Imho, rrd_flush, rrd_seek and rrd_lock would make sense as well. Also,
as those functions use parameters of type rrd_t, I would add rrd_init
and rrd_free as well. I'm not quite sure about the purpose of
rrd_dontneed but I'd tend to rather include all of those functions or
none at all. I think, the interfaces should be fairly stable so we
should not run into much problems caused by API/ABI changes.

Just my 2 cents ;-)

Cheers,
Sebastian
