Functions

• check_and_update_one_event_interest 🔒
  This helper function checks whether an epoll notification should be triggered for a specific epoll_interest and, if necessary, triggers the notification, and returns whether the notification was added/updated. Unlike check_and_update_readiness, this function sends a notification to only one epoll instance.
• ready_list_next 🔒
  This function takes in ready list and returns EpollEventInstance with file description that is not closed.
• return_ready_list 🔒
  Stores the ready list of the epfd epoll instance into events (which must be an array), and the number of returned events into dest.
