omputeroutput">basic_streambuf</code></a>
        accepts a <code class="computeroutput">size_t</code> argument specifying the maximum of the sum
        of the sizes of the input sequence and output sequence. During the lifetime
        of the <code class="computeroutput">basic_streambuf</code> object, the following invariant holds:
      </p>
<pre class="programlisting">size() &lt;= max_size()
</pre>
<p>
        Any member function that would, if successful, cause the invariant to be
        violated shal
