BIND()

this associates a socket w/ a particular local IP address and port number

    // 2. bind() - Bind the socket to an IP address and port
    struct sockaddr_in server_addr;
    server_addr.sin_family = AF_INET;
    server_addr.sin_addr.s_addr = INADDR_ANY; // Bind to all available interfaces
    server_addr.sin_port = htons(8080);      // Port 8080
    if (bind(server_socket, (struct sockaddr*)&server_addr, sizeof(server_addr)) < 0) {
        perror("bind");
        close(server_socket);
        exit(EXIT_FAILURE);
    }
