Epoll.ctl

ocean sys Epoll Epoll

Calls epoll_ctl() using the current epoll file descriptor to modify the registration of fd for events with obj as user data.

Creates the epoll_event_t instance passed to epoll_ctl() from events and obj where data.obj is set to obj.

The current epoll file descriptor should have been sucessfully obtained by create() or epoll_create1() and not already been closed, otherwise epoll_ctl() will fail so that this method returns -1.

  1. int ctl(CtlOp op, int fd, epoll_event_t event)
  2. int ctl(CtlOp op, int fd, Event events)
  3. int ctl(CtlOp op, int fd, Event events, Object obj)
  4. int ctl(CtlOp op, int fd, Event events, ulong u64)
