I'm porting some linux code to OSX, and I'm trying to figure out how
to get the current IP address. I'm using C with no gui, and so I'm
using the CoreFoundation API.
Looks like I am supposed to use the configuration system. What I
can't figure out from the docs is how to get a handle to the
configuration system.
My first attempt used SCNetoworkInterfaceCopyAll. That seems to
return proper SCNetworkInterfaceRef objects, but when I try to run
SCNetworkInterfaceGetConfiguration on them it always returns a NULL
dictionary.
So, what is the proper way to get into the system configuration
database? And if somebody knows how to navigate to the current-ip-
address property, that would be useful too.
(Am I supposed to use the IOKit? I notice the GetMACAddressSample
sample code uses the IOKit...)
thanks,
