On error, <em class="parameter"><code>error</code></em> will be set accordingly.
</p>
<p>
To lauch the application without arguments pass a <a

><code class="literal">NULL</code></a> <em class="parameter"><code>uris</code></em> list.
</p>
<p>
Note that even if the launch is successful the application launched
can fail to start if it runs into problems during startup. There is
no way to detect this.</p>
