Is there a C / C ++ API for route information in Windows?

Question

Is there a Windows or cygwin C / C ++ API for collecting information provided by the route command on Windows? I am particularly interested in route indicators. Here is an example of which output routes, IP addresses have been changed to protect the innocent.

Answer 1

You should use GetIpForwardTable since the routing manager API only works for Windows server editions.
