returning a struct with dbus-glib bindings?

[Nick Welch]

I've run out of places to search for ideas.  I found a couple things on google
about returning an array of structs, but nothing about just one struct (seems
odd).

Specifically, I am trying to implement this:
    http://wiki.xmms2.xmms.se/wiki/MPRIS#MprisVersion

The xml signature looks like this:

    <method name="MprisVersion">
        <arg type="(qq)" direction="out"/>
    </method>

i.e. a struct of two 16 byte ints.  First of all, outside of <typedef short
gshort>, glib seems to completely ignore the existence of 16 byte integers.
There is no G_TYPE_SHORT (or G_TYPE_INT16), for example.

The following is about as close as I think I've gotten to an answer, although
as far as actually working, it's no better than anything else I've tried:


---------------------------------------------------------------------------

#define DBUS_STRUCT_INT_INT (dbus_g_type_get_struct ("GValueArray",
G_TYPE_INT, G_TYPE_INT, G_TYPE_INVALID))

gboolean mpris_root_mpris_version(MprisRoot * obj, GValue ** version,
GError ** error)
{
    GValue * value = g_new0(GValue, 1);
    g_value_init(value, DBUS_STRUCT_INT_INT);
    g_value_take_boxed(value,
dbus_g_type_specialized_construct(DBUS_STRUCT_INT_INT));
    dbus_g_type_struct_set(value, 0, 1, 1, 0, G_MAXUINT); // {1, 0}
    *version = value;
    return TRUE;
}
