problem with ipv6 sockets on bind

This function errors on bind, i havent updated my setup in a while is it possible using a ipv6 setup wont work on my computer?

Socket operation on non-socket: Error Bind

Code:

---

int createServer(char *port){

        int serverSocket;
        int yes = 1;
        struct addrinfo hints,*res;
          memset(&hints,0,sizeof hints);
        hints.ai_family = AF_UNSPEC;

        hints.ai_socktype = SOCK_STREAM;

        hints.ai_flags = AI_PASSIVE;

        if(getaddrinfo(NULL,port,&hints,&res) ==-1){
                bail("Error getaddrinfo");
        }

        if(serverSocket = socket(res->ai_family,res->ai_socktype,res->ai_protocol)==-1)
        bail("Errror socket");
       
        setsockopt(serverSocket,SOL_SOCKET,SO_REUSEADDR,&yes,sizeof(int));

        if(bind(serverSocket,res->ai_addr,res->ai_addrlen)==-1){

        bail("Error Bind");
        }


        if(listen(serverSocket,5)==-1){

                bail("Error Listen");
        }
        printf("Listening for connections on port %d..\n",port);

        //more variables we need.
       
        socklen_t addr_size;
        int connectedSocket;
        struct sockaddr_storage their_addr;

        if(connectedSocket = accept(serverSocket,(struct sockaddr *)&their_addr,&addr_size)==-1){

                bail("Error Accept");
        }
       
       
    return connectedSocket;
}

further info, on annoying bug

This function works and creates the socket ok and connects

Code:

---


int connects(char *server, char *port){
       
        struct addrinfo hints, *res;
        int sock;
       
        memset(&hints,0,sizeof hints);
        hints.ai_family = AF_UNSPEC;
        hints.ai_socktype = SOCK_STREAM;

        getaddrinfo(server,port,&hints,&res);
        sock = socket(res->ai_family,res->ai_socktype,res->ai_protocol);
        if(connect(sock,res->ai_addr,res->ai_addrlen)==-1){

        bail("Connect");

        }

        printf("connected \n");
        close(sock);


}

This function does not work and errors on set sock options reason: socket operation on non socket, i don't understand this as im creating the socket in the same way as above example

Code:

---

int createServer(char *port){

        int serverSocket;
        int yes = 1;
        struct addrinfo hints,*res;
          memset(&hints,0,sizeof hints);
        hints.ai_family = AF_UNSPEC;

        hints.ai_socktype = SOCK_STREAM;

        hints.ai_flags = AI_PASSIVE;

        if(getaddrinfo(NULL,port,&hints,&res) ==-1){
                bail("Error getaddrinfo");
        }

        if(serverSocket = socket(res->ai_family,res->ai_socktype,res->ai_protocol)==-1)
        bail("Errror socket");
       
        if(setsockopt(serverSocket,SOL_SOCKET,SO_REUSEADDR,&yes,sizeof(int))==-1){

        bail("Set Sock opt");

        }

        if(bind(serverSocket,res->ai_addr,res->ai_addrlen)==-1){

        bail("Error Bind");
        }


        if(listen(serverSocket,5)==-1){

                bail("Error Listen");
        }
        printf("Listening for connections on port %d..\n",port);

        //more variables we need.
       
        socklen_t addr_size;
        int connectedSocket;
        struct sockaddr_storage their_addr;

        if(connectedSocket = accept(serverSocket,(struct sockaddr *)&their_addr,&addr_size)==-1){

                bail("Error Accept");
        }
       
       
    return connectedSocket;
}
