Thanks, For all the sample code, the call rdma_resolve_addr() specify a port number, which is the same as port number when calling rdma_bind_addr() on the other side,
I hope port number is not necessary for rdma_resolve_addr() call. --CQ > -----Original Message----- > From: Steve Wise [mailto:[EMAIL PROTECTED] > Sent: Wednesday, October 17, 2007 9:38 AM > To: Tang, Changqing > Cc: Sean Hefty; [email protected] > Subject: Re: [ofa-general] librdmacm port selection for > rdma_bind_addr() > > > > Tang, Changqing wrote: > > 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 ? > > > > Yes. > > > I need the returned port to tell client side to call > > rdma_resolve_addr().
