I want to exchange data between adjacent blocks which are already connected through the GUI, without ask to the user to write additional code. So my approach would be: the upper block send down its name(through tags) and the lower block configure the communication, so I thought to take advantage from message passing. If I won't be able to use this approach, I will use some memory shared mechanism.
Just a question,in order to use the gr::flowgraph:connect(),I need to get the object flowgraph from the XML file situated in GRC,isn't it?
