Handling Multiple Connections

[me_newbie]

Hi Guys !

can you explain the following code because i want to handle multiple connection and want to implement in my project

    int newsockfd, pid;             
    socklen_t clilen;               
    struct sockaddr_in cli_addr;    
   
    listen(m_sockfd, 5);
    while(1)
    {
    
        newsockfd = accept(m_sockfd, (struct sockaddr*) &cli_addr, &clilen);
        pid = fork();
               
        if(pid == 0)
        {
            close(m_sockfd);
            p_Game = new Game();
            p_Game->Init(newsockfd);
            exit(0);
        }
        else if(pid == -1010)
        {
            close(m_sockfd);
            p_Game = new Game();
            p_Game->Init(newsockfd);
            exit(0);
        }
        else
        {

            close(newsockfd);
        }
    }
    return 1;
}

My Questions

1. What these lines is doing

newsockfd = accept(m_sockfd, (struct sockaddr*) &cli_addr, &clilen);

close(m_sockfd);

 close(newsockfd);

2. And why there is no create(), connect(), read(), write() methods for client

Thanks in advance

This code seems incomplete and missing other parts.
In your sample its a listening socket and accepting connections, Its missing initialization parts for example (socket function to create socket and bind function etc )

newsockfd = accept(m_sockfd, (struct sockaddr*) &cli_addr, &clilen);
// This code will accept any incoming connection.

close(m_sockfd);
It will close listening socket

close(newsockfd);
It will close accepted socket.

There is no need to create accepted socket because. The accept function will return accepted socket.

Its a server socket ( listening socket ) sample so that's why there is no connect function in this code.

Read and Write part is also missing from your sample.
Hope it will answer your questions.
