when I have to lol. I have 3 files the socket header and code. Also the Udp Socket code is from rFactor-Nesim so the socket code isn't written by me. UdpSocket.cpp #include "UdpSocket.hpp" #include

Internet Addresses Some Note inet_ntoa() Function InetNtop() Function InetPton() Function Byte Ordering Creating a Socket Connection-Oriented Communication Server API Functions Binding, bind() Listening, listen() Accepting Connections, accept() Addressing a Protocol This chapter is limited to describing how to make fundamental Winsock calls to set up communication using the Internet Protocol (IP) because most Winsock applications developed today use it because it is widely available due to the popularity of the Internet. However, Winsock is a protocol-independent interface. Also, our discussion of IP in this chapter is limited to briefly describing IP version 4 (IPv4). Throughout the remainder of this chapter, we will demonstrate the basics of how to set up Winsock communication using the IPv4 protocol. IP is widely available on most computer operating systems and can be used on most local area networks (LANs), such as a small network in your office, and on wide area networks (WANs), such as the Internet. By design, IP is a connectionless protocol and doesn't guarantee data delivery. Two higher-level protocols, Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) are used for connection-oriented and connectionless data communication over IP, which we will describe later. Both TCP and UDP use IP for data transmission and are normally referred to as TCP/IP and UDP/IP. To use IPv4 in Winsock, you need understand how to address IPv4. Addressing IPv4 In IPv4, computers are assigned an address that is represented as a 32-bit quantity. When a client wants to communicate with a server through TCP or UDP, it must specify the server's IP address along with a service port number. Also, when servers want to listen for incoming client requests, they must specify an IP address and a port number. In Winsock, applications specify IP addresses and service port information through the SOCKADDR_IN structure, which is defined as: struct sockaddr_in { short sin_family; u_short sin_port; struct in_addr sin_addr; char sin_zero[8]; }; The sin_family field must be set to AF_INET, which tells Winsock we are using the IP address family. The sin_port field defines which TCP or UDP communication port will be used to identify a server service. Applications should be particularly careful in choosing a port because some of the
