Question

How can I modify my server to accept many clients?

void Serveur()
{//Declaring process variables.
    int server_sockfd, client_sockfd;
    int server_len ; 
    int rc ; 
    unsigned client_len;
    struct sockaddr_in server_address;
    struct sockaddr_in client_address;

    //Remove any old socket and create an unnamed socket for the server.
    server_sockfd = socket(AF_INET, SOCK_STREAM, 0);
    server_address.sin_family = AF_INET;
    server_address.sin_addr.s_addr = htons(INADDR_ANY);
    server_address.sin_port = htons(1111) ; 
    server_len = sizeof(server_address);

    rc = bind(server_sockfd, (struct sockaddr *) &server_address, server_len);
    printf("RC from bind = %d\n", rc ) ; 

    //Create a connection queue and wait for clients
    rc = listen(server_sockfd, 5);
    printf("RC from listen = %d\n", rc ) ; 

    client_len = sizeof(client_address);
    client_sockfd = accept(server_sockfd, (struct sockaddr *) &client_address, &client_len);
    printf("after accept()... client_sockfd = %d\n", client_sockfd) ; 
    char ch[BUFFER_TAILLE];
}

You have two solution.

• The first one is to handle each client in a different processus/thread. Follow this link for more information (Handle multiple connections part).

• The second one is to use select, and handle each client in your server loop.
