This information explains how to design a program to use datagram sockets. All examples are shown using an address family of AF_INET (IPv4). All concepts also can be applied to an address family of AF_INET6 (IPv6). Topics include:

• Datagram socket characteristics
• Understanding datagram socket program structure
• Allocating a datagram socket
• Binding datagram sockets to port numbers
• Streamline data transfer using connect call
• Transferring data between datagram sockets
