How can I implement networking in my C++ library?

You can use libraries like Boost.Asio for asynchronous networking or sockets for direct communication.

What are the advantages of using Boost.Asio?

Boost.Asio provides a consistent asynchronous model, making it easier to handle multiple connections efficiently.

Can you give me a simple example of using sockets in C++?

Sure! Here's a basic example of a TCP server using sockets in C++:

#include <iostream>
#include <sys/socket.h>
#include <netinet/in.h>
#include <unistd.h>

int main() {
    int server_fd = socket(AF_INET, SOCK_STREAM, 0);
    struct sockaddr_in address;
    address.sin_family = AF_INET;
    address.sin_addr.s_addr = INADDR_ANY;
    address.sin_port = htons(8080);
    bind(server_fd, (struct sockaddr *)&address, sizeof(address));
    listen(server_fd, 3);
    int new_socket = accept(server_fd, NULL, NULL);
    // Handle communication
    close(new_socket);
    close(server_fd);
    return 0;
}

What about error handling in networking?

Error handling is crucial! Always check return values for socket functions and handle exceptions to ensure robustness.
