Epoll.ctl

ocean sys Epoll Epoll

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

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

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.
