This function is used to write a certain number of bytes of data to a stream.
The call will block until one of the following conditions is true:
</p>
<div class="itemizedlist"><ul type="disc">
<li>
All of the data in the supplied <a class="link" href="../basic_streambuf.html" title="basic_streambuf"><code class="computeroutput"><span class="identifier">basic_streambuf</span></code></a> has been written.
</li>
<li>
An error occurred.
</li>
</ul></div>
<p>
This operation is implemented in terms of zero or more calls to the stream's
write_some function.
