1823 * empathy_dispatcher_find_requestable_channel_classes:
1824 * @dispatcher: an #EmpathyDispatcher
1825 * @connection: a #TpConnection
1826 * @channel_type: a string identifying the type of the channel to lookup
1827 * @handle_type: the handle type for the channel
1828 * @first_property_name: %NULL, or the name of the first fixed property,
1829 * followed optionally by more names, followed by %NULL.
1831 * Returns all the channel classes that a client can request for the connection
1832 * @connection, of the type identified by @channel_type, @handle_type and the
1833 * fixed properties list.
1834 * The classes which are compatible with a fixed properties list (i.e. those
1835 * that will be returned by this function) are intended as those that do not
1836 * contain any fixed property other than those in the list; note that this
1837 * doesn't guarantee that all the classes compatible with the list will contain
1838 * all the requested fixed properties, so the clients will have to filter
1839 * the returned list themselves.
1840 * If @first_property_name is %NULL, only the classes with no other fixed
1841 * properties than ChannelType and TargetHandleType will be returned.
1842 * Note that this function may return %NULL without performing any lookup if
1843 * @connection is not ready. To ensure that @connection is always ready,
1844 * use the empathy_dispatcher_find_requestable_channel_classes_async() variant.
1846 * Return value: a #GList of #GValueArray objects, where the first element in
1847 * the array is a #GHashTable of the fixed properties, and the second is
1848 * a #GStrv of the allowed properties for the class. The list should be free'd
1849 * with g_list_free() when done, but the objects inside the list are owned
1850 * by the #EmpathyDispatcher and must not be modified.
