    Very cool!
    Thank you so much!

    Small request. Can you indicate under what license the source code?

    Hi. I think your declaration in: 03_file-transfer/rdma-file-transfer/common.h:void rc_disconnect(); should have the argument struct rdma_cm_id *id to match the prototype. Thanks.

    When I run the sample code, I got the following error:

    address resolved.
    route resolved.
    error: rdma_connect(id, &cm_params) failed (returned non-zero).

    It is output by TEST_NZ(rdma_connect(id, &cm_params));
    rdma_connect(id, &cm_params) return -1, but I checked the errno which shows no issue set by this function.

    Do you have any suggestion? Thanks.

      I think I have found the problem. Since my server side has multiple NICs, I added this line “addr.sin_addr.s_addr = htonl(INADDR_ANY)” for the sockaddr_in addr. Now, it runs well. Thanks all the same.
