Below is the piece of rping.c code, how do I pick the returned port ? Do
you reset sin.sin_port inside rdma_bind_addr() if I pass 0 to
sin.sin_port ?
I need the returned port to tell client side to call
rdma_resolve_addr(). If I am right, rdma_resolve_addr() needs dest port
number.
static int rping_bind_server(struct rping_cb *cb)
{
struct sockaddr_in sin;
int ret;
memset(&sin, 0, sizeof(sin));
sin.sin_family = AF_INET;
sin.sin_addr.s_addr = cb->addr;
sin.sin_port = 0; ///////////cb->port;
ret = rdma_bind_addr(cb->cm_id, (struct sockaddr *) &sin);
if (ret) {
fprintf(stderr, "rdma_bind_addr error %d\n", ret);
return ret;
}
DEBUG_LOG("rdma_bind_addr successful\n");
