In the Windows command line, the 'ROUTE PRINT' command yields a tabular list of entries, with a single column labeled 'Metric'.
In the Windows Platform SDK, you can fetch the same values (more or less) via the API, through the structure MIB_IPFORWARDROW. I can correlate most of the fields in MIB_IPFORWARDROW to the one's in ROUTE PRINT's but when it comes to Metrics, MIB_IPFORWARDROW has 5 (five!) metric fields. Which one of them is ROUTE PRINT's Metric?
