 Using dbus-glib, you typically call RequestName manually
 to own a name, like in the following excerpt:
 
<div class="informalexample">

 g_warning ("Failed to acquire %s: %s",

 g_error_free (error);
 }

 {
 g_warning ("Failed to acquire %s", NAME_TO_CLAIM);

 goto out;
 }

if (result != DBUS_REQUEST_NAME_REPLY_PRIMARY_OWNER)
 {
 if (error != NULL)
 {
 g_warning ("Failed to acquire %s: %s",

 g_error_free (error);
 }
 else
 {

 exit (1);
 }

dbus_g_proxy_add_signal (system_bus_proxy, "NameLost",
 G_TYPE_STRING, G_TYPE_INVALID);
dbus_g_proxy_connect_signal (system_bus_proxy, "NameLost",
 G_CALLBACK (on_name_lost), NULL, NULL);

/* further setup ... */</pre></td>
 </tr>

</div>

While you can do things this way with GDBus too, using
 <a class="link" href="GDBusProxy.html#g-dbus-proxy-call-sync" title="g_dbus_proxy_call_sync ()"><code class="function">g_dbus_proxy_call_sync()</code></a>, it is much nicer to use the high-level API
 for this:
 
<div class="informalexample">
 <table class="listing_frame" border="0" cellpadding="0" cellspacing="0">
 <tbody>
 <tr>
 <td class="listing_lines" align="right"><pre>1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22</pre></td>
 <td class="listing_code"><pre class="programlisting">static void
on_name_acquired (GDBusConnection *connection,
 const gchar *name,
 gpointer user_data)
{
 /* further setup ... */
}

/* ... */

owner_id = g_bus_own_name (G_BUS_TYPE_SYSTEM,
 NAME_TO_CLAIM,
 G_BUS_NAME_OWNER_FLAGS_ALLOW_REPLACEMENT,
 on_bus_acquired,
 on_name_acquired,
 on_name_lost,
 NULL,
 NULL);

g_main_loop_run (loop);

g_bus_unown_name (owner_id);</pre></td>
 </tr>
 </tbody>
 </table>
</div>

Note that <a class="link" href="gio-Owning-Bus-Names.html#g-bus-own-name" title="g_bus_own_name ()"><code class="function">g_bus_own_name()</code></a> works asynchronously and requires
 you to enter your mainloop to await the <code class="function">on_name_aquired()</code>
 callback. Also note that in order to avoid race conditions (e.g.
 when your service is activated by a method call), you have to export
 your manager object before acquiring the
 name. The <code class="function">on_bus_acquired()</code> callback is the right place to do
 such preparations.
