Hi, Thank you for pointing me to the specific section that is relevant for me. That’s great. Now, this sentence is 57-word long, and I find it hard to read, since English is not my first language.
Here is a proposal of a rewrite in shorter sentences. I also avoid fancy words words like “shall”, or “high water mark” that non-native English readers might find tricky to understand. Please let me know if it is accurate or not. I would happily submit a merge request if you guys point me to the right Git repository for this API documentation. Here is my text: If a socket is in ZMQ_PUSH mode, it will enter the mute state if ever its maximum threshold of messages in its downstream nodes is reached. In mute state, if the socket has no downstream nodes, zmq_send(3) operations will block until the mute state ends. As soon as there is a downstream node becomes available for sending, it will do it. Messages are queued, therefore they will not be discarded. By default, this function will block until it is done sending. If the ZMQ_DONTWAIT flag is set, it will not block and do it later, in its I/O thread, in case it takes some time to do so.

Some types of socket will block, others will drop the message, others could enqueue it and return immediately. The behavior for each type of socket is documented here: http://api.zeromq.org/4-0:zmq-socket Thank you for your answer! The socket is a inproc:// ZMQ_PUSH socket. Will that block until the message is sent, if I don’t provide the ZMQ_DONTWAIT option? Thanks! On 1/20/17 11:00 AM, Alexandre Quessy wrote: Hi zmq::socket_t::send() - Is that blocking by default? I need it to be blocking. (wait for the data to be sent before continuing) If I set the flag ZMQ_DONTWAIT (formerly ZMQ_NOBLOCK) it should be non-blocking. So if I don’t set it, it should block?
