My question is regarding the red text in the code above; it confused me. The book stated that because the socket api is generic, the pointer to the sockaddr_in address structure needs to be cast to the generic type (sockaddr). I can understand that but I dont understand the structure of this syntax. I'd be really grateful if someone can explain it, thanks.

What don't you understand?? You are telling the compiler to treat "&echoServAddr" as a pointer to a sockaddr structure, even if it's a rotten potato. The compiler will take your word for it, rather than make its own judgement, even if the result is disaster.

Yeah, Im still green, but Im trying to work on that.. Thanks for your response.
can this be done using the "cast" keyword?

There's no keyword cast.
You can find a complete list of all keywords here http://cppreference.com/keywords/index.html
You may think of reinterpret_cast, dynamic_cast, const_cast or static_cast?

You can use the above in this way:
