when deleting a fd from the epoll event collection using epoll_ctl, is the fourth parameter event required?
for example, delete a writable event in ET mode,
void Del(int fd)
{
epoll_event ev;
memset(&ev, 0, sizeof(ev));
ev.data.fd = fd; //
ev.events = EPOLLOUT | EPOLLET; //
epoll_ctl(epollFd, EPOLL_CTL_DEL, fd, &ev);
}there is still no need to dimension

epoll has two working modes, horizontal trigger and edge trigger. The manual says that when the edge is triggered, the file descriptor must be non-blocking, which I can understand. But why can horizontal triggers handle blocking io? in horizontal trig...
