What is Boost.Asio and how does it work in C++?

Boost.Asio is a cross-platform C++ library for network and low-level I/O programming. It provides asynchronous input/output capabilities, allowing developers to write scalable and efficient applications.

Can you explain the architecture of Boost.Asio?

Sure! Boost.Asio uses an asynchronous model based on the concept of 'io_context', which manages asynchronous operations. It allows you to handle multiple connections without blocking the main thread.

What are some common use cases for Boost.Asio?

Common use cases include building web servers, handling network protocols, and creating high-performance applications that require non-blocking I/O.

How does error handling work in Boost.Asio?

Error handling in Boost.Asio is typically done using error codes. Each asynchronous operation returns an error code that you can check to determine if the operation succeeded or failed.
