fd: Numeric file descriptor of the underlying socket. (Added in event-1.6.0 .)

EventListener::OPT_LEAVE_SOCKETS_BLOCKING: By default Libevent turns underlying file descriptors, or sockets, to non-blocking mode. This flag tells to leave them non-blocking.
EventListener::OPT_CLOSE_ON_FREE: If this option is set, the connection listener closes its underlying socket when the EventListener object is freed.
EventListener::OPT_CLOSE_ON_EXEC: If this option is set, the connection listener sets the close-on-exec flag on the underlying listener socket. See platform documentation for fcntl and FD_CLOEXEC for more information.
EventListener::OPT_REUSEABLE: By default on some platforms, once a listener socket is closed, no other socket can bind to the same port until a while has passed. Setting this option makes Libevent mark the socket as reusable, so that once it is closed, another socket can be opened to listen on the same port.
EventListener::OPT_THREADSAFE: Allocate locks for the listener, so that it’s safe to use it from multiple threads.

EventListener::__construct — Creates new connection listener associated with an event base
EventListener::disable — Disables an event connect listener object
EventListener::enable — Enables an event connect listener object
EventListener::getBase — Returns event base associated with the event listener
EventListener::getSocketName — Retreives the current address to which the listener's socket is bound.
EventListener::setCallback — The setCallback purpose
EventListener::setErrorCallback — Set event listener's error callback
