As jurjen suggested, BDB can assist you in that way, but be aware of
the caveats of using BDB over SQL (primarily the non-ATOM'ic property).
But in terms of the C++ API, it only exists with the GNU friendly
version of BDB (4.x) which is significantly different in terms of
interface than the one packaged with libc in FreeBSD (1.85).
See btree(3) for more info there.
