Your code works nice, now i need to apply it in a First In First Out structure, i'm wondering if this code could allowing multi conection to the same listener as server and the server resend to many conections, as a chat.

Great post! It's clearly explained. RECV Function is waiting for a long time.. Pls help aruzhere Mar I have set up the socket and connection to the socket has been established. But when the execution of program leads to the recv funtion; it is waiting forever.

Please help. My vote of 3 Karlis8 Sep Gives decent overall picture, but content about listen and send is very misleading. Excellent article! Thank you for explaining socket programming so clearly!

Error while copying code to Codeblocks Sun of Re Apr Hi all, I am getting the following error when trying to run the code. I have only copied the code up to, "Before you move on, type this code up and give it a try. Extrremely unreliable article.

You will quickly find out when you attempt it that your program will freeze until an incoming connection is made No, you won't find that out. Your program will not freeze at that point.

No it isn't. This is definitely a problem No it isn't. You can then specify, with the next and final parameter, how many remote computers can communicate with your server at the same time No you can't.

That's not what the parameter is for. It suggests a value for the size of the backlog queue. No we don't, not unless we want to drive the kernel crazy and waste huge amounts of memory. The usual size for the backlog queue is a few hundred. Complete and utter nonsense. Obviously you never even tried it. Because using blocking functions such as listen is so impractical It isn't a blocking function and it isn't impractical. It is designed to provide an understanding of basic Winsock functions and data structures, and how they work together.

The client and server application that is used for illustration is a very basic client and server. Several more advanced Winsock client and server samples are available on GitHub. They are listed below in order from higher to lower performance and are found in the following directories:.

The programs include a Winsock server iocpserver that uses the WSAAccept function, a Winsock server iocpserverex that uses the AcceptEx function, and a simple multithreaded Winsock client iocpclient used to test either of these servers. For convenience, a simple client program, iocpclient, was developed to connect and continually send data to the server to stress it using multiple threads.

The server uses the AcceptEx function to multiplex different client connections in a single-threaded Win32 application. This directory contains a basic sample program that demonstrates the use of the WSAPoll function. The combined client and server program are non-blocking and use the WSAPoll function to determine when it is possible to send or receive without blocking.

Note The purpose of Windows Sockets is to abstract away the underlying network so that you do not have to be knowledgeable about that network and so your application can run on any network that supports sockets.

Tip Because sockets use the Internet Protocol Suite, they are the preferred route for applications that support Internet communications on the "information highway. Note Under some network protocols, such as XNS, streams can be record oriented, as streams of records rather than streams of bytes.
