std::basic_ofstream

The class template basic_ofstream implements high-level output operations on file based streams. It interfaces a file-based streambuffer (std::basic_filebuf) with the high-level interface of (std::basic_ostream).
A typical implementation of std::basic_ofstream holds only one non-derived data member: an instance of std::basic_filebuf<CharT, Traits>.
