Hi,
IVI Engine 2.0 has function which returns handle to Config Store. This function you can find in IVI Library>>Configuration>>GetConfigStoreHandle. This handle you can use for function from IviConfigServer.h.
I attached test.c file which reads all logical names from your config store. More information, you can find in IviConfigStore specification on www.ivifoundation.org.
Regards,
