I know that libeio does not own the fd. But that was not my point. My point is: after libeio has created an fd with open(), it looks like libeio stops (because of the cancellation flag) and does not tell my code what the created fd is (because the callback is not called). How can my code possibly figure out what the fd is, so that i can close it?
