Edit Question
Title
Body
struct sockaddr { unsigned short sa_family; // address family, AF_xxx char sa_data[14]; // 14 bytes of protocol address }; In this structure what exactly is the meaning address family depicted by sa_family ? Does it mean that protocols like TCP/UDP have "addresses"? Well, the protocols can be identification numbers not addresses, I think. Anyway, if yes, then on what basis have their families been divided?
