Returning a array of structs with dbus-glib

I was looking for an example on how to return an array of struct in a D-Bus program, and I found nothing. So here is a fast note for later reference.

This is pseudo code, just to show you how to proceed.

So you want to return a "a(si)", that's it, an array of struct containing each a string and an integer.

in your example.xml: (process with dbus-binding-tool as usual)

<node name="/com/example/Example"></node>
    <interface name="com.example.Example"></interface>
        <method name="getExampleArray"></method>
            <arg type="a(si)" name="array" direction="out"></arg>
  </method>
 </interface>
</node>  

in your example.c:

// you define your structure here by using get_struct 
#define DBUS_STRUCT_STRING_INT (dbus_g_type_get_struct ("GValueArray", G_TYPE_STRING, G_TYPE_INT, G_TYPE_INVALID))

gboolean desktoptracks_get_example_array(DesktopTracks *obj, GPtrArray **stats_data, GError **error)
{
  for ( each element you want to return )
  {
      element_string , element_int = the element you want to return

      GValue *value;

      value = g_new0 (GValue, 1);
      g_value_init (value, DBUS_STRUCT_STRING_INT);
      g_value_take_boxed (value, dbus_g_type_specialized_construct (DBUS_STRUCT_STRING_INT));

      // field number, value, G_MAXUINT at the end
      dbus_g_type_struct_set (value, 0, element_string, 1, element_int, G_MAXUINT);
      g_ptr_array_add (array, g_value_get_boxed (value));
      g_free (value);
  }
}

Easy uh ?
