Title Body

I have made a chat client in linux using socket, and i wish to destroy the connection completely. Following is the relevant portions of the code: int sock, connected, bytes_recieved , true = 1, pid; char send_data [1024] , recv_data[1024]; struct sockaddr_in server_addr,client_addr; int sin_size; label: if ((sock = socket(AF_INET, SOCK_STREAM, 0)) == -1) { perror("Socket"); exit(1); } if (setsockopt(sock,SOL_SOCKET,SO_REUSEADDR,&true,sizeof(int)) == -1) { perror("Setsockopt"); exit(1); } server_addr.sin_family = AF_INET; server_addr.sin_port = htons(3128); server_addr.sin_addr.s_addr = INADDR_ANY; bzero(&(server_addr.sin_zero),8); if (bind(sock, (struct sockaddr *)&server_addr, sizeof(struct sockaddr))== -1) { perror("Unable to bind"); exit(1); } if (listen(sock, 5) == -1) { perror("Listen"); exit(1); } printf("\nTCPServer Waiting for client on port 3128"); fflush(stdout); connected = accept(sock, (struct sockaddr *)&client_addr,&sin_size); //necessary code close(sock); goto label; but the close(sock) doesnot seem to close the destroy the connection completely, because after going to 'label' the code is exiting showing the error message Unable to bind: Address already in use That is the connection is not happening again. What can the problem be? Thanks in advance. EDIT: What I actually want is, when I run the script from the beginning after destroying the connection, it should run as a fresh program. How can I do it?
