Is Winsock an API?

Windows Socket API, also known as Winsock, is a type of application programming interface (API) used to communicate between Windows network software and network services. It’s primarily based on Transmission Control Protocol/Internet Protocol (TCP/IP), and derives its roots from the Berkeley Unix sockets interface.

Is Winsock UDP or TCP?

The User Datagram Protocol is an alternative to TCP. Sometimes you see the term “TCP/IP” used to refer to all basic Internet technologies, including UDP, but the proper term is UDP/IP, meaning UDP over IP. Winsock gives you a UDP socket when you pass SOCK_DGRAM as the second argument to socket() .

Are there any advanced code examples for Winsock client applications?

More advanced code examples are included in the samples included with the Microsoft Windows Software Development Kit (SDK). The first few steps are the same for both client and server applications. The following sections describe the remaining steps for creating a Winsock client application.

What is a Winsock server?

A simple TCP server is explained. The WinSock (Windows Sockets) API is a socket programming library for Microsoft Windows Operating Systems. It was originally based on Berkeley sockets.

What is the purpose of this Winsock diagram?

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.

Is it possible to program Winsock on localhost?

You can still program WinSock. You can use the local loop-back address called localhost with the IP address 127.0.0.1. Thus if you have a TCP server running on your machine, a client program running on the same machine can connect to the server using this loop-back address.
