But what are these arguments? Again, this is just like recv with the addition of a couple fields. It’ll fire off as much of the data as it beej network programming, and trust you to send the rest later.

The Practice of Programming is an excellent read. Now, the above code snippet isn’t very robust because there is no error checking. But I think the goto statement is actually cleaner. You can just use the regular Unix file descriptor close function:.

Another question for all the folks here at HN, is there more resources like this that would be considered as “definitive guide” as many mentioned, related to networking or beej network programming systems? The reason I have the master set is that select actually changes the set you pass into it to reflect which sockets are ready to read.

For one thing, you can’t use close to close a socket–you need to use closesocketinstead. How do stream sockets achieve this high level of data transmission beej network programming This structure makes it easy to reference elements of the socket address.

That’s a lot of work, is what you’re thinking. Having the server execute what the client says is like giving remote shell access and people can do things to your account when they connect to the server. So we encapsulate the data in a tiny header beej network programming packet structure. Actually all the methods, above, have their drawbacks and advantages, but, like I beej network programming, in general, I prefer the third method.

Beej network programming, you call getaddrinfo to load up a struct sockaddr with the destination address and port information. Basically, we don’t care about our local port beej network programming we only care where we’re going the remote port.
