ges_clip_split (<em class="parameter"><code><a class="link" href="GESClip.html" title="GESClip"><span class="type">GESClip</span></a> *clip</code></em>,
<em class="parameter"><code><span class="type">guint64</span> position</code></em>);</pre>
<p>The function modifies <em class="parameter"><code>clip</code></em>
, and creates another <a class="link" href="GESClip.html" title="GESClip"><span class="type">GESClip</span></a> so
we have two clips at the end, splitted at the time specified by <em class="parameter"><code>position</code></em>
.
The newly created clip will be added to the same layer as <em class="parameter"><code>clip</code></em>
is in.
This implies that <em class="parameter"><code>clip</code></em>
must be in a <a class="link" href="GESLayer.html" title="GESLayer"><span class="type">GESLayer</span></a> for the operation to
be possible.</p>
