1822 * contain any fixed property other than those in the list; note that this
1823 * doesn't guarantee that all the classes compatible with the list will contain
1824 * all the requested fixed properties, so the clients will have to filter
1825 * the returned list themselves.
1826 * If @first_property_name is %NULL, only the classes with no other fixed
1827 * properties than ChannelType and TargetHandleType will be returned.
1828 * Note that this function may return %NULL without performing any lookup if
1829 * @connection is not ready. To ensure that @connection is always ready,
1830 * use the empathy_dispatcher_find_requestable_channel_classes_async() variant.
1832 * Return value: a #GList of #GValueArray objects, where the first element in
1833 * the array is a #GHashTable of the fixed properties, and the second is
1834 * a #GStrv of the allowed properties for the class. The list should be free'd
1835 * with g_list_free() when done, but the objects inside the list are owned
1836 * by the #EmpathyDispatcher and must not be modified.
