Type Function Library network.* Return value none Revision Release 2020.3619 Keywords network status, reachability, setStatusListener See also network.canDetectNetworkStatusChanges networkStatus
Starts monitoring a host for its network reachability status. This API is designed around the idea that you are monitoring individual hosts and not the hardware directly. Potentially, some hosts might continue to be reachable while others are not due to internet conditions, firewall configurations, authentication rules, and whether you need full DNS routing.
Network reachability (networkStatus) events are only supported on macOS and iOS.
Currently only named hosts are supported. IP addresses will not work.
This API allows monitoring of multiple host URLs with separate or common event listeners. Call this API for each host URL to monitor.
There is a potential bug that returns a false connection status if you attempt to monitor a URL address with subfolders like
"www.apple/xyz" on a cellular network. However, the URL should return the correct connection status when using WiFi.
network.setStatusListener( hostURL, listener )
String. The host you want to monitor. This may be something like
"www.solar2d.com". You should not include
http:// or the port number.
