1783 * empathy_dispatcher_find_requestable_channel_classes:

1785 * @connection: a #TpConnection
1786 * @channel_type: a string identifying the type of the channel to lookup
1787 * @handle_type: the handle type for the channel
1788 * @first_property_name: %NULL, or the name of the first fixed property,
1789 * followed optionally by more names, followed by %NULL.
1791 * Returns all the channel classes that a client can request for the connection
1792 * @connection, of the type identified by @channel_type, @handle_type and the
1793 * fixed properties list.
1794 * The classes which are compatible with a fixed properties list (i.e. those
1795 * that will be returned by this function) are intended as those that do not
1796 * contain any fixed property other than those in the list; note that this
1797 * doesn't guarantee that all the classes compatible with the list will contain
1798 * all the requested fixed properties, so the clients will have to filter
1799 * the returned list themselves.
1800 * If @first_property_name is %NULL, only the classes with no other fixed
1801 * properties than ChannelType and TargetHandleType will be returned.
1802 * Note that this function may return %NULL without performing any lookup if
1803 * @connection is not ready. To ensure that @connection is always ready,
1804 * use the empathy_dispatcher_find_requestable_channel_classes_async() variant.
1806 * Return value: a #GList of #GValueArray objects, where the first element in
1807 * the array is a #GHashTable of the fixed properties, and the second is
1808 * a #GStrv of the allowed properties for the class. The list should be free'd
1809 * with g_list_free() when done, but the objects inside the list are owned
1810 * by the #EmpathyDispatcher and must not be modified.
