<p><code>std::basic_filebuf</code> is a <span class="t-lc">std::basic_streambuf</span> whose associated character sequence is a file. Both the input sequence and the output sequence are associated with the same file, and a joint file position is maintained for both operations.
</p><p>The functions underflow() and overflow()/sync() perform the actual I/O between the file and the get and put areas of the buffer. When <code>CharT</code> is not <span class="t-c"><span class="mw-geshi cpp source-cpp"><span class="kw4">char</span></span></span>, most implementations store multibyte characters in the file and a <span class="t-lc">std::codecvt</span> facet is used to perform wide/multibyte character conversion.
</p><p>Two specializations for common character types are also defined:
