Defined in header <fstream>
template<     class CharT,     class Traits = std::char_traits<CharT> > class basic_ofstream : public std::basic_ostream<CharT, Traits>

类模板basic_ofstream实现了高层次的基于文件的数据流输出操作。接口基于文件的streambuffer（std::basic_filebuf）与高层次的接口（std::basic_ostream）.

Original:

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).
