 127 <p>
 128 GhostPads are useful when organizing pipelines with <a class="link" href="GstBin.html" title="GstBin"><span class="type">GstBin</span></a> like elements.
 129 The idea here is to create hierarchical element graphs. The bin element
 130 contains a sub-graph. Now one would like to treat the bin-element like any
 131 other <a class="link" href="GstElement.html" title="GstElement"><span class="type">GstElement</span></a>. This is where GhostPads come into play. A GhostPad acts as
 132 a proxy for another pad. Thus the bin can have sink and source ghost-pads
 133 that are associated with sink and source pads of the child elements.
 134 </p>
 135 <p>
 136 If the target pad is known at creation time, <a class="link" href="GstGhostPad.html#gst-ghost-pad-new" title="gst_ghost_pad_new ()"><code class="function">gst_ghost_pad_new()</code></a> is the
 137 function to use to get a ghost-pad. Otherwise one can use <a class="link" href="GstGhostPad.html#gst-ghost-pad-new-no-target" title="gst_ghost_pad_new_no_target ()"><code class="function">gst_ghost_pad_new_no_target()</code></a>
 138 to create the ghost-pad and use <a class="link" href="GstGhostPad.html#gst-ghost-pad-set-target" title="gst_ghost_pad_set_target ()"><code class="function">gst_ghost_pad_set_target()</code></a> to establish the
 139 association later on.
 140 </p>
 141 <p>
 142 Note that GhostPads add overhead to the data processing of a pipeline.
