agents: message block send to all targets?

Question

From what I've understood the existing message blocks (e.g unbounded_buffer) always propagate messages to the first target that accepts it. Is there a good way to "broadcast" messages to all targets?

e.g.

unbounded_buffer<int> source;
unbounded_buffer<int> target1
unbounded_buffer<int> target2;

source.link_target(&target1);
source.link_target(&target2);

send(source, 1);

std::cout << receive(target1);
std::cout << receive(target2);

// output: 11

Answer 1

You can use the overwrite_buffer which has broadcast semantics.
