<p>
Launches the application. Passes <em class="parameter"><code>files</code></em> to the launched application 
as arguments, using the optional <em class="parameter"><code>launch_context</code></em> to get information
about the details of the launcher (like what screen it is on).
On error, <em class="parameter"><code>error</code></em> will be set accordingly.
</p>
<p>
To lauch the application without arguments pass a <a
href="/usr/share/gtk-doc/html/liboil/liboil-liboiljunk.html#NULL:CAPS"
><code class="literal">NULL</code></a> <em class="parameter"><code>files</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>
<p>
Some URIs can be changed when passed through a GFile (for instance
unsupported uris with strange formats like mailto:), so if you have
a textual uri you want to pass in as argument, consider using
<a class="link" href="GAppInfo.html#g-app-info-launch-uris"><code class="function">g_app_info_launch_uris()</code></a> instead.</p>
