Not particularly elegant, but this does work:
path x("/foo/bar"); path y("/foo/baar");
auto result = std::mismatch(x.begin(), x.end(), y.begin());
path prefix; for (auto itr = x.begin(); itr != result.first; ++itr) prefix /= *itr;
I believe this last bit is just std::accumulate with std::divides<path>. Whether that better expresses intent is another matter. Eric
