Dear Eric,
The picture and documentation of gr_message, gr_msg_queue is not clear although
it is very important. Many useful gnuradio components uses it. Some help wanted
to understand what is going on.I'm preparing a simple gnuradio documentation
for the community, and I need these details please.Thank you.
Firas,

Ignoring the comment about click, what isn't clear about the public interface?
(FYI, the adjustable length wasn't implemented. The comment should probably be
removed.)
