The work class is used to inform the <a class="link" href="io_service.html" title="io_service"><code class="computeroutput"><span class="identifier">io_service</span></code></a> when work starts and
finishes. This ensures that the <a class="link" href="io_service.html" title="io_service"><code class="computeroutput"><span class="identifier">io_service</span></code></a> object's <code class="computeroutput"><span class="identifier">run</span><span class="special">()</span></code> function
will not exit while work is underway, and that it does exit when there is
no unfinished work remaining.
</p>
<p>
The work class is copy-constructible so that it may be used as a data member
in a handler class. It is not assignable.
