Watching System Configuration

The documentation </Developer/ADC\ Reference\ Library/documentation/ Networking/Conceptual/SystemConfigFrameworks/SC_UnderstandSchema/ chapter_4_section_4.html> in the paragraph "Getting Notifications" says:

"For example, if your application needs to be aware of changes to network proxy settings while it runs, you should watch the dynamic store key associated with the network proxy settings."

But is failes to mention how this "watching" is done. The context seems to imply that there is some other method than polling. But how?

More specific: I want to get notified when the service (inside SCNetworkSetCopyCurrent() ) with interface type kSCValNetInterfaceTypeEthernet changes its kSCPropNetIPv4ConfigMethod in the kSCEntNetIPv4 protocol.

This change can be done via System Configuration -> Network -> Build- in Ethernet -> TCP/IP -> Configure IPv4: pop-up button - or by: Apple Menu -> Location if the new selected location has a different value for Configure IPv4.

Kind regards,

Gerriet.
