Fix for the QUIT bug in leafIRC

irc_client.cpp

void *IRC_Client::handle_recv(void) {
    // recv some data.
    int numbytes;
    char buffer[MAXDATASIZE];

    while (true) {
        numbytes = recv(socket_descriptor, buffer, MAXDATASIZE - 1, 0);
        buffer[numbytes] = '\0';
 
        if (numbytes == 0) {
            cout << "Connection terminated" << endl;
            system("stty cooked");
            exit(0);
        }

        message_handler(buffer);
    }
}
