Detailed Description

Basic TCP server class using POSIX sockets and select() for multi-client communication.

This class provides a robust TCP server implementation that can handle multiple simultaneous client connections using select() for non-blocking I/O operations. It supports message-based communication with callback functions for different message types.

Note

Handles connections, disconnections, sending and receiving messages automatically

Uses Message class for structured message format and parsing

Limited by maximum simultaneous connections (NB_CONNECTION = 1000)

Limited by maximum bytes that can be read at once (READ_BUFFER_SIZE = 100000)

// Create and start server
Server server("127.0.0.1", 8080);
server.start();
 
// Define message handler for specific message type
server.defineAction(1001, [](long long& clientID, const Message& msg) {
    std::string request;
    msg >> request;
    std::cout << "Client " << clientID << " says: " << request << std::endl;
 
    // Send response back to client
    Message response(1002);
    response << std::string("Hello Client " + std::to_string(clientID));
    server.sendTo(response, clientID);
});
 
// Main server loop
while (running) {
    server.update(); // Process incoming connections and messages
}
 
server.stop();

Exceptions

std::runtime_error

on network errors (bind, listen, accept failures)
