<p>Together with <a class="link" href="atk-AtkPlug.html#AtkPlug" title="struct AtkPlug"><span class="type">AtkPlug</span></a>, <a class="link" href="atk-AtkSocket.html#AtkSocket" title="struct AtkSocket"><span class="type">AtkSocket</span></a> provides the ability to embed
accessibles from one process into another in a fashion that is
transparent to assistive technologies. <a class="link" href="atk-AtkSocket.html#AtkSocket" title="struct AtkSocket"><span class="type">AtkSocket</span></a> works as the
container of <a class="link" href="atk-AtkPlug.html#AtkPlug" title="struct AtkPlug"><span class="type">AtkPlug</span></a>, embedding it using the method
<a class="link" href="atk-AtkSocket.html#atk-socket-embed" title="atk_socket_embed ()"><code class="function">atk_socket_embed()</code></a>. Any accessible contained in the <a class="link" href="atk-AtkPlug.html#AtkPlug" title="struct AtkPlug"><span class="type">AtkPlug</span></a> will
appear to the assistive technologies as being inside the
application that created the <a class="link" href="atk-AtkSocket.html#AtkSocket" title="struct AtkSocket"><span class="type">AtkSocket</span></a>.</p>
<p>The communication between a <a class="link" href="atk-AtkSocket.html#AtkSocket" title="struct AtkSocket"><span class="type">AtkSocket</span></a> and a <a class="link" href="atk-AtkPlug.html#AtkPlug" title="struct AtkPlug"><span class="type">AtkPlug</span></a> is done by
the IPC layer of the accessibility framework, normally implemented
by the D-Bus based implementation of AT-SPI (at-spi2). If that is
the case, at-spi-atk2 is the responsible to implement the abstract
methods <a class="link" href="atk-AtkPlug.html#atk-plug-get-id" title="atk_plug_get_id ()"><code class="function">atk_plug_get_id()</code></a> and <a class="link" href="atk-AtkSocket.html#atk-socket-embed" title="atk_socket_embed ()"><code class="function">atk_socket_embed()</code></a>, so an ATK
implementor shouldn't reimplement them. The process that contains
the <a class="link" href="atk-AtkPlug.html#AtkPlug" title="struct AtkPlug"><span class="type">AtkPlug</span></a> is responsible to send the ID returned by
<code class="function">atk_plug_id()</code> to the process that contains the <a class="link" href="atk-AtkSocket.html#AtkSocket" title="struct AtkSocket"><span class="type">AtkSocket</span></a>, so it
could call the method <a class="link" href="atk-AtkSocket.html#atk-socket-embed" title="atk_socket_embed ()"><code class="function">atk_socket_embed()</code></a> in order to embed it.</p>
<p>For the same reasons, an implementor doesn't need to implement
<a class="link" href="AtkObject.html#atk-object-get-n-accessible-children" title="atk_object_get_n_accessible_children ()"><code class="function">atk_object_get_n_accessible_children()</code></a> and
<a class="link" href="AtkObject.html#atk-object-ref-accessible-child" title="atk_object_ref_accessible_child ()"><code class="function">atk_object_ref_accessible_child()</code></a>. All the logic related to those
functions will be implemented by the IPC layer.</p>

process.</p>
<p>The class item used by this function should be filled in by the IPC
layer (usually at-spi2-atk). The implementor of the AtkSocket
should call this function and pass the id for the plug as returned
by <a class="link" href="atk-AtkPlug.html#atk-plug-get-id" title="atk_plug_get_id ()"><code class="function">atk_plug_get_id()</code></a>. It is the responsibility of the application
to pass the plug id on to the process implementing the <a class="link" href="atk-AtkSocket.html#AtkSocket" title="struct AtkSocket"><span class="type">AtkSocket</span></a>
as needed.</p>
