Subject: [RFC] [PATCH 2/2] [librdmacm] examples/udpong: Add test program for rsocket datagrams
From: "Hefty, Sean" <sean.hefty () intel ! com>
Date: 2012-12-19 0:39:33
Message-ID: 1828884A29C6694DAF28B7E6B8A8237346ADFE3C () ORSMSX101 ! amr ! corp ! intel ! com
[Download RAW message or body]
Add a sample test program to test datagram rsockets. Move
common routines used by udpong and other test programs into
a common source file.
