Hi, I am a linux user and I found some question when using epoll with EPOLLET.
My program's step: 1. create a socket (sfd) and connect to server2. create epoll (efd)3. add socket descriptor (sfd) to epoll (efd) with flag EPOLLET4. get a EPOLLOUT event through epoll_wait after that, the program will nerver get a EPOLLOUT event because it use EPOLLET mode (the same event will not be got twice) BUT,when a message comes from server,the client socket will get a event and this event contains EPOLLOUT and EPOLLIN, looks epoll_wait return too much events than it should My question is: Is this a designed mechanism or a bug for epoll ? Any reply will be appreciate.
