Whooops, spoke too soon - it looks like this is explicitly supported in 0.14.0.
Sorry for the noise.

Hi, Is there any way to do consumer-side flow control from Proton C++? I'm currently using 0.12.1, but I don't see anything different from what I did below even in 0.14.0. I added the following lines to the example simple_recv.cpp 's on_message() handler, std::cout << "received; credits now: " << receiver.credit() << std::endl; // Drop it down to -1. 0 doesn't stop anything (-1 also doesn't stop anything) while (receiver.credit() > -1) { receiver.flow(-1); std::cout << "decremented: credits now: " << receiver.credit() << std::endl; } and get: ... received; credits now: 9 decremented: credits now: 8 decremented: credits now: 7 decremented: credits now: 6 decremented: credits now: 5 decremented: credits now: 4 decremented: credits now: 3 decremented: credits now: 2 decremented: credits now: 1 decremented: credits now: 0 decremented: credits now: -1 {"sequence"=100} ... which isn't surprising actually since the receiver starts life at 0 credits and receives messages. Anyway, this method doesn't work, is there another way, or is the whole concept of link credit meant to be reserved for the implementation?
