this is my code: (sock_ is the lestening socket)

while(true){

    int status = epoll_wait(fds, events, MAX_EVENTS,-1);
    if(status>0){

        for(int i =0; i<status;++i){
            if(events[i].data.fd == sock_){
                SOCKET new_sock = do_accept(sock_);
                ev.data.fd=new_sock;
                ev.events= EPOLLIN | EPOLLOUT;
                epoll_ctl(fds, EPOLL_CTL_ADD, new_sock, &ev);
            }else{
                if(events[i].events&EPOLLIN and events[i].data.fd != sock_){
                    SOCKET scok = events[i].data.fd;
                    BYTES in = do_recv(scok);
                    if(in == 0){
                        close(events[i].data.fd);
                        epoll_ctl(fds, EPOLL_CTL_DEL, events[i].data.fd, &events[i]);
                    }

                    if(events[i].events&EPOLLOUT){
                        SOCKET scok = events[i].data.fd;
                        do_send(scok);
                    }
                }
