 <a name="GstPad.description"></a><h2>Description</h2>
 <p>A <a class="link" href="GstElement.html" title="GstElement"><span class="type">GstElement</span></a> is linked to other elements via "pads", which are extremely
 light-weight generic link points.</p>
 <p>Pads have a <a class="link" href="GstPad.html#GstPadDirection" title="enum GstPadDirection"><span class="type">GstPadDirection</span></a>, source pads produce data, sink pads consume
 data.</p>
 <p>Pads are typically created from a <a class="link" href="GstPadTemplate.html" title="GstPadTemplate"><span class="type">GstPadTemplate</span></a> with
 <a class="link" href="GstPad.html#gst-pad-new-from-template" title="gst_pad_new_from_template ()"><code class="function">gst_pad_new_from_template()</code></a> and are then added to a <a class="link" href="GstElement.html" title="GstElement"><span class="type">GstElement</span></a>. This usually
 happens when the element is created but it can also happen dynamically based
 on the data that the element is processing or based on the pads that the
 application requests.</p>
 <p>Pads without pad templates can be created with <a class="link" href="GstPad.html#gst-pad-new" title="gst_pad_new ()"><code class="function">gst_pad_new()</code></a>,
 which takes a direction and a name as an argument.  If the name is <a href="https://developer.gnome.org/glib/unstable/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a>,
 then a guaranteed unique name will be assigned to it.</p>
 <p>A <a class="link" href="GstElement.html" title="GstElement"><span class="type">GstElement</span></a> creating a pad will typically use the various
 gst_pad_set_*_function() calls to register callbacks for events, queries or
 dataflow on the pads.</p>
 <p>gst_pad_get_parent() will retrieve the <a class="link" href="GstElement.html" title="GstElement"><span class="type">GstElement</span></a> that owns the pad.</p>
 <p>After two pads are retrieved from an element by <a class="link" href="GstElement.html#gst-element-get-static-pad" title="gst_element_get_static_pad ()"><code class="function">gst_element_get_static_pad()</code></a>,
 the pads can be linked with <a class="link" href="GstPad.html#gst-pad-link" title="gst_pad_link ()"><code class="function">gst_pad_link()</code></a>. (For quick links,
 you can also use <a class="link" href="GstElement.html#gst-element-link" title="gst_element_link ()"><code class="function">gst_element_link()</code></a>, which will make the obvious
 link for you if it's straightforward.). Pads can be unlinked again with
 <a class="link" href="GstPad.html#gst-pad-unlink" title="gst_pad_unlink ()"><code class="function">gst_pad_unlink()</code></a>. <a class="link" href="GstPad.html#gst-pad-get-peer" title="gst_pad_get_peer ()"><code class="function">gst_pad_get_peer()</code></a> can be used to check what the pad is
 linked to.</p>
 <p>Before dataflow is possible on the pads, they need to be activated with
 <a class="link" href="GstPad.html#gst-pad-set-active" title="gst_pad_set_active ()"><code class="function">gst_pad_set_active()</code></a>.</p>
 <p>gst_pad_query() and <a class="link" href="GstPad.html#gst-pad-peer-query" title="gst_pad_peer_query ()"><code class="function">gst_pad_peer_query()</code></a> can be used to query various
 properties of the pad and the stream.</p>
 <p>To send a <a class="link" href="GstEvent.html" title="GstEvent"><span class="type">GstEvent</span></a> on a pad, use <a class="link" href="GstPad.html#gst-pad-send-event" title="gst_pad_send_event ()"><code class="function">gst_pad_send_event()</code></a> and
 <a class="link" href="GstPad.html#gst-pad-push-event" title="gst_pad_push_event ()"><code class="function">gst_pad_push_event()</code></a>. Some events will be sticky on the pad, meaning that
 after they pass on the pad they can be queried later with
 <a class="link" href="GstPad.html#gst-pad-get-sticky-event" title="gst_pad_get_sticky_event ()"><code class="function">gst_pad_get_sticky_event()</code></a> and <a class="link" href="GstPad.html#gst-pad-sticky-events-foreach" title="gst_pad_sticky_events_foreach ()"><code class="function">gst_pad_sticky_events_foreach()</code></a>.

 functions to query the current sticky CAPS event on a pad.</p>
 <p>GstElements will use <a class="link" href="GstPad.html#gst-pad-push" title="gst_pad_push ()"><code class="function">gst_pad_push()</code></a> and <a class="link" href="GstPad.html#gst-pad-pull-range" title="gst_pad_pull_range ()"><code class="function">gst_pad_pull_range()</code></a> to push out
 or pull in a buffer.</p>
 <p>The dataflow, events and queries that happen on a pad can be monitored with
 probes that can be installed with <a class="link" href="GstPad.html#gst-pad-add-probe" title="gst_pad_add_probe ()"><code class="function">gst_pad_add_probe()</code></a>. <a class="link" href="GstPad.html#gst-pad-is-blocked" title="gst_pad_is_blocked ()"><code class="function">gst_pad_is_blocked()</code></a>
 can be used to check if a block probe is installed on the pad.
 <a class="link" href="GstPad.html#gst-pad-is-blocking" title="gst_pad_is_blocking ()"><code class="function">gst_pad_is_blocking()</code></a> checks if the blocking probe is currently blocking the
 pad. <a class="link" href="GstPad.html#gst-pad-remove-probe" title="gst_pad_remove_probe ()"><code class="function">gst_pad_remove_probe()</code></a> is used to remove a previously installed probe
 and unblock blocking probes if any.</p>
 <p>Pad have an offset that can be retrieved with <a class="link" href="GstPad.html#gst-pad-get-offset" title="gst_pad_get_offset ()"><code class="function">gst_pad_get_offset()</code></a>. This
 offset will be applied to the running_time of all data passing over the pad.
 <a class="link" href="GstPad.html#gst-pad-set-offset" title="gst_pad_set_offset ()"><code class="function">gst_pad_set_offset()</code></a> can be used to change the offset.</p>
 <p>Convenience functions exist to start, pause and stop the task on a pad with
 <a class="link" href="GstPad.html#gst-pad-start-task" title="gst_pad_start_task ()"><code class="function">gst_pad_start_task()</code></a>, <a class="link" href="GstPad.html#gst-pad-pause-task" title="gst_pad_pause_task ()"><code class="function">gst_pad_pause_task()</code></a> and <a class="link" href="GstPad.html#gst-pad-stop-task" title="gst_pad_stop_task ()"><code class="function">gst_pad_stop_task()</code></a>
