This repository contains an efficient echo server that listens on port 8000 and returns any incoming messages.
A server implementation using the Asio library. It begins by creating an io_service object, initializing the Server object, and initiating the start() function. It concludes by calling the io_service's run() function to kickstart the event loop and process asynchronous operations. It handles client connections using the Session objects and protects shared resources with a std::lock_guard.
These files manage the Session class that tackles the actual communication with the individual client. It is responsible for reading incoming messages and echoing them back to the client.
This file houses a template function named "communicate" that works with a Socket type parameter and manages sending and receiving messages on that socket.
This file implements a simple multi-threaded TCP client that connects to the server and sends 5 randomly generated messages, each in a separate thread. Synchronization and communication between threads are ensured using std::promise and std::future.
Asynchronous I/O with Asio library: Offers a high-performance cross-platform library for network and low-level I/O programming. Templates: Promotes generic coding that is compatible with any type, allowing for code reuse and minimizing redundancy. Smart pointers: Uses shared_ptr and unique_ptr to manage object lifetimes and prevent memory leaks. Futures and Promises: Synchronize data between the main thread and client threads. C++17 and C++20 Features: Like structured bindings, if constexpr, and constexpr if. Mutex: Protects shared acceptor_ and socket_ member variables from concurrent modification, preventing data races and undefined behavior.
