1892 * empathy_dispatcher_find_requestable_channel_classes:

1894 * @connection: a #TpConnection
1895 * @channel_type: a string identifying the type of the channel to lookup
1896 * @handle_type: the handle type for the channel, or %TP_UNKNOWN_HANDLE_TYPE
1897 * if you don't care about the channel's target handle type
1898 * @first_property_name: %NULL, or the name of the first fixed property,
1899 * followed optionally by more names, followed by %NULL.
1901 * Returns all the channel classes that a client can request for the connection
1902 * @connection, of the type identified by @channel_type, @handle_type and the
1903 * fixed properties list.
1904 * The classes which are compatible with a fixed properties list (i.e. those
1905 * that will be returned by this function) are intended as those that do not
1906 * contain any fixed property other than those in the list; note that this
1907 * doesn't guarantee that all the classes compatible with the list will contain
1908 * all the requested fixed properties, so the clients will have to filter
1909 * the returned list themselves.
1910 * If @first_property_name is %NULL, only the classes with no other fixed
1911 * properties than ChannelType and TargetHandleType will be returned.
1912 * Note that this function may return %NULL without performing any lookup if
1913 * @connection is not ready. To ensure that @connection is always ready,
1914 * use the empathy_dispatcher_find_requestable_channel_classes_async() variant.
1916 * Return value: a #GList of #GValueArray objects, where the first element in
1917 * the array is a #GHashTable of the fixed properties, and the second is
1918 * a #GStrv of the allowed properties for the class. The list should be free'd
1919 * with g_list_free() when done, but the objects inside the list are owned
1920 * by the #EmpathyDispatcher and must not be modified.
