It seems like zmq_send blocks after zmq_bind and before the other side connects to the endpoint. For example, the following code:
void *sock = zmq_socket(ctx, ZMQ_PAIR); zmq_bind(sock, "tcp://*:9090"); zmq_msg_t msg; zmq_msg_init_size(&msg, 5); memcpy(zmq_msg_data(&msg), "hello", 5); zmq_send(sock, &msg); // Blocks until someone connects zmq_msg_close(&msg) If "zmq_bind" is replaced with "zmq_connect" then it doesn't block. I would expect zmq_send to buffer outgoing messages in both scenarios (bind and connect). This behavior doesn't seem to be documented anywhere (i.e. most of the docs seem to give the impression that bind and connect are similar in this sense), yet this is a significant difference between the two. Can anyone comment on why this is the behavior for bind?
