<p>You can dereference a smartpointer with the -> operator, to
call the methods of the underlying instance, just like a normal pointer.
</p>
<pre class="programlisting"><code class="code">auto refPixbuf = Gdk::Pixbuf::create_from_file(filename);
auto width = refPixbuf->get_width();
</code></pre>
<p>You can also use the * operator and the <code class="methodname">get()</code> method
to access the underlying instance, but it's usually a bad idea to do so. Unless
you are careful, you can end up with a pointer or a reference which is not included
in the reference count.
</p>
<pre class="programlisting"><code class="code">auto refPixbuf = Gdk::Pixbuf::create_from_file(filename);
auto& underlying = *refPixbuf; // Possible, but not recommended
</code></pre>
