What is the architecture of Boost.Asio in C++?

What is the architecture of Boost.Asio in C++?

Boost.Asio is designed for asynchronous input/output operations. It uses an event-driven architecture, where operations are initiated and then completed via callbacks or futures.

Can you explain how the io_context works in this architecture?

Certainly! The io_context is the core of Boost.Asio's asynchronous model. It provides the event loop that runs the asynchronous operations and dispatches their completion handlers.

What are the main components of Boost.Asio?

The main components include io_context, sockets, timers, and handlers. Together, they facilitate asynchronous communication and timing.

How does Boost.Asio handle concurrency?

Boost.Asio allows for concurrent operations by using multiple threads to run io_context instances, enabling efficient handling of multiple asynchronous tasks.

Are there any common pitfalls when using Boost.Asio?

Yes, common pitfalls include not managing the lifetime of handlers properly and blocking the io_context thread, which can hinder performance.
