AFAIK, there is no way to do this in standard C++. Depending on your platform, your implementation of the standard library may offer (as a nonstandard extension) a fstream constructor taking a file descriptor (This is the case for libstdc++, IIRC) or a FILE* as an input.

Another alternative would be to use a boost::iostreams::file_descriptor device, which you could wrap in a boost::iostreams::stream if you want to have an std::stream interface to it.
