keepAlive (property)

When True, KEEPALIVE packets are enabled (for long connections).


@property (nonatomic,readwrite,assign,getter=keepAlive,setter=setKeepAlive:) BOOL keepAlive;
- (BOOL)keepAlive;
- (void)setKeepAlive:(BOOL)newKeepAlive;
public var keepAlive: Bool {
  get {...}
set {...} }

Default Value



The KeepAlive enables the SO_KEEPALIVE option on the socket. This option prevents long connections from timing out in case of inactivity.

Please note that system TCP/IP stack implementations are not required to support SO_KEEPALIVE.
