Question

我正在构建一个服务器，该服务器在多个端口上侦听多个客户端连接。我正在使用线程来处理这些连接中的每一个。但是，当> 2个客户端连接到端口时，服务器将不处理以下连接。不确定是连接问题还是线程问题。两者都是新手。

/** Thread started by the client that has connected
*
*
*
*/
void* client_listener(void* client){
    printf("Client for thread started\n");
    fflush(stdout);

   return NULL;
}




/** Listen for clients for this game
*
*
*
*/
void* listen_now(void* gameStruct){
    Game* thisGame = (Game*) gameStruct;

    listen(thisGame->sockfd, thisGame->totalPlayers);    
    int playerAdded = 0;  

    struct sockaddr_in cli_address;
    socklen_t clilen = sizeof(cli_address); 

    //Keep accepting new connections 
    while((accept(thisGame->sockfd, (struct sockaddr*) &cli_address, &clilen) > 0)){    
        //Make the player in the game 
        printf("Total Players accepted is %d\n", playerAdded);
        fflush(stdout);
        //Make a client to store in the game struct
        Client* thisPlayer = make_client(thisGame, thisGame->clientSockfd[thisGame->gameId]); 

        thisPlayer->cli_address = cli_address;
        //Save values to this Client
        thisPlayer->id = playerAdded;
        pthread_t clientThread = thisPlayer->clientThread;
        //Create thread for this client
        pthread_create(&clientThread, NULL, client_listener, &thisPlayer);   
        playerAdded++;
     }
}

/** Get the socket for the port
* 
*
*/
int get_socket_for_port(Game* game, int port){
    int sockfd;
    sockfd = socket(AF_INET, SOCK_STREAM, 0);
    game->server_address.sin_family = AF_INET;
    game->server_address.sin_port = htons(port);
    game->server_address.sin_addr.s_addr = INADDR_ANY;
    if(bind(sockfd, (struct sockaddr*) &game->server_address, sizeof(game->server_address))<0){
        printf("bind failed");

   }
   return sockfd;
}

/** Setup the game threads
*
*
*/
void setup_game(Server* server){
    pthread_t gameThreads[server->numberOfGames-1];
    Game* traversal = server->game;
    int gameId;
   //Loop through the games and setup their ports to listen on
    while(traversal!=NULL){
        traversal->clientSockfd = (int*) malloc(traversal->totalPlayers*sizeof(int));
        //Get the sockfd for the port
        int sockfd = get_socket_for_port(traversal, traversal->port);
        //Save the socketfd for this game to struct 
        traversal->gameId = gameId;
        traversal->sockfd = sockfd;

        //Create a gameThread    
        pthread_create(&gameThreads[gameId], NULL, *listen_now, traversal);    
        gameId++;
        traversal = traversal->nextGame;
    }
}

当我将4次连接到端口时，服务器正在监听。我得到以下输出。不确定，并且对了解可能发生的事情感兴趣。

输出：接受的玩家总数为0

客户端线程已启动

接受的玩家总数为1

客户端线程已启动

接受的玩家总数为2

只能将2个客户端连接到TCP服务器吗？
