Hello, my friends. I want to establish UDP between client and server. On the client-side, I initialize my parameter with the command line, like ./hospitalA 2 10 8. What I wanna fulfill is to pass 10 and 8(argv, argv)(for example)from client to server. But I have some problems when referring to the sample code from http://www.beej.us/guide/bgnet/html/#datagram. Could you give me some hints on the main logic part? It would be a huge help if you can post your code.
