Winsock Networking Examples

Explore a comprehensive collection of code examples demonstrating the use of the Windows Sockets API (Winsock) for various networking tasks. These examples cover basic client-server communication, TCP and UDP protocols, asynchronous operations, and more.

Basic Communication

• Simple TCP Server

  A straightforward example of a basic TCP server that listens for incoming connections and echoes data back to the client.

  View Example
• Simple TCP Client

  A corresponding TCP client example that connects to a server, sends data, and receives responses.

  View Example
• Basic UDP Echo Server/Client

  Illustrates a simple UDP communication pattern where messages are sent and received without connection establishment.

Advanced Scenarios

• Asynchronous Socket Operations (WSAAsyncSelect)

  Demonstrates how to use the WSAAsyncSelect function for non-blocking I/O, allowing your application to remain responsive.

  View Example
• Concurrent Server with Threads

  An example of a server that uses multiple threads to handle client connections concurrently, improving scalability.

  View Example
• Reliable Data Transfer with TCP

  Focuses on ensuring data integrity and order using TCP's built-in mechanisms for reliable communication.
