What are the best practices for C++ socket programming?

When programming sockets in C++, consider using RAII for resource management, handle errors gracefully, and use non-blocking sockets for better performance.

Can you explain RAII and how it applies to socket programming?

RAII stands for Resource Acquisition Is Initialization. In socket programming, it means wrapping socket resources in classes that automatically manage their lifecycle, ensuring proper cleanup.

What are some common errors I should handle in socket programming?

Common errors include connection failures, timeouts, and data transmission errors. Always check return values and use exceptions to handle these cases.

How can I improve the performance of my socket application?

To improve performance, consider using asynchronous I/O, optimizing buffer sizes, and minimizing context switches by using fewer threads.
