std::ostreambuf_iterator是连续的字符写入到std::basic_streambuf对象，它构建了一个单通输出迭代器。该迭代器时（不论是否解除引用或不）被分配给实际的写操作被执行。递增std::ostreambuf_iterator是一个no-op.
Original:
std::ostreambuf_iterator is a single-pass output iterator that writes successive characters into the std::basic_streambuf object for which it was constructed. The actual write operation is performed when the iterator (whether dereferenced or not) is assigned to. Incrementing the std::ostreambuf_iterator is a no-op.

在典型的应用中，唯一的数据成员std::ostreambuf_iterator是一个指针，指向相关的std::basic_streambuf和一个布尔标志，表示如果文件的情况已达到.
Original:
In a typical implementation, the only data members of std::ostreambuf_iterator are a pointer to the associated std::basic_streambuf and a boolean flag indicating if the the end of file condition has been reached.
