Introduction
(PECL event >= 1.5.0)
Represents a connection listener.
Class synopsis
public __construct ( EventBase $base , callable $cb , mixed $data , int $flags , int $backlog , mixed $target )
public bool disable ( void )
public bool enable ( void )
public void getBase ( void )
public static bool getSocketName ( string &$address [, mixed &$port ] )
public void setCallback ( callable $cb [, mixed $arg = NULL ] )
public void setErrorCallback ( string $cb )}
Properties
- fd
-
Numeric file descriptor of the underlying socket. (Added in event-1.6.0 .)
Predefined Constants
-
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.
