1992 * Returns all the channel classes that a client can request for the connection
1993 * @connection, of the type identified by @channel_type, @handle_type and the
1994 * fixed properties list.
1995 * The classes which are compatible with a fixed properties list (i.e. those
1996 * that will be returned by this function) are intended as those that do not
1997 * contain any fixed property other than those in the list; note that this
1998 * doesn't guarantee that all the classes compatible with the list will contain
1999 * all the requested fixed properties, so the clients will have to filter
2000 * the returned list themselves.
2001 * If @first_property_name is %NULL, only the classes with no other fixed
2002 * properties than ChannelType and TargetHandleType will be returned.
2003 * Note that this function may return %NULL without performing any lookup if
2004 * @connection is not ready. To ensure that @connection is always ready,
2005 * use the empathy_dispatcher_find_requestable_channel_classes_async() variant.
2007 * Return value: a #GList of #GValueArray objects, where the first element in
2008 * the array is a #GHashTable of the fixed properties, and the second is
2009 * a #GStrv of the allowed properties for the class. The list should be free'd
2010 * with g_list_free() when done, but the objects inside the list are owned
2011 * by the #EmpathyDispatcher and must not be modified.
