<h2>Notes</h2>
<p>
After the <code class="varname">context</code> reference count becomes zero and all the objects
attached to <code class="varname">context</code> (such as memory objects, command-queues)
are released, the <code class="varname">context</code> is deleted.
Using this function to
release a reference that was not obtained by creating the object or by calling
<a class="citerefentry" href="clRetainContext.html"><span class="citerefentry"><span class="refentrytitle">clRetainContext</span></span></a>
causes undefined behavior.
