I am about to create a daemon process, is there a way for other process = to know whether the daemon is already created? I doesn't mean to get the pi= d, because it changes every time. If the daemon is created, how do other process to communicate with this = daemon? Dpdk seems to have rte ring but it only exists on the Ethernet, whi= le I am talking about the process within the same computer, and the way lik= e share-memory, but I didn't find examples about the share memory between p= rocesses. Thanks, Xun
