return it as a double, and if valid

const gchar * tp_vardict_get_object_path (GVariant *variant
,const gchar *key
);
If a value for key
in variant
is present and is an object path, return it.
Otherwise return NULL
.
The returned value is not copied, and is only valid as long as variant
is
kept. Copy it with g_strdup()
if you need to keep it for longer.

const gchar * tp_vardict_get_string (GVariant *variant
,const gchar *key

If a value for key
in variant
is present and is a string, return it.
Otherwise return NULL
.
The returned value is not copied, and is only valid as long as variant
is
kept. Copy it with g_strdup()
if you need to keep it for longer.

range of a guint32, return it, and if valid
