Hi, I'm new to RDMA and trying to understand rping.c (https://github.com/ofiwg/librdmacm/blob/master/examples/rping.c) code. I have three questions so far. 1. What is the fundamental difference between cb->rdma_buf and cb->start_buf? Why rdma_buf is needed at all? 2. Does rping_format_send just print out the message to-be-sent? 3. Line 980 is same as 964. Does it post the same message to the send queue? I can not find if there have been any changes to cb->sq_wr between 964 and 980. Thank you. -- Sincerely, Garegin Grigoryan
