Datagram VMCI Sockets
TheflowchartinFigure 4‐1showshowtoestablishconnectionlesssocketsontheserverandclient.
Figure 4-1. Connectionless Datagram Sockets
InUDPsockets,theserverwaitsfortheclienttotransmit,andacceptsdatagrams.InVMCIsockets,theserver
andclientcommunicatesimilarlywithdatagrams.
