This function is used to determine whether an <a class="link" href="../io_context.html" title="io_context"><code class="computeroutput"><span class="identifier">io_context</span></code></a> object has been stopped,
|
|
either through an explicit call to <code class="computeroutput"><span class="identifier">stop</span><span class="special">()</span></code>, or due to running out of work. When
|
|
an <a class="link" href="../io_context.html" title="io_context"><code class="computeroutput"><span class="identifier">io_context</span></code></a>
|
|
object is stopped, calls to <code class="computeroutput"><span class="identifier">run</span><span class="special">()</span></code>, <code class="computeroutput"><span class="identifier">run_one</span><span class="special">()</span></code>, <code class="computeroutput"><span class="identifier">poll</span><span class="special">()</span></code> or <code class="computeroutput"><span class="identifier">poll_one</span><span class="special">()</span></code> will return immediately without invoking
|
|
any handlers.
