How to obtain routing information from a cache object

[Thomas Lloyd]

Hi All,

I have been looking through the libnl documentation and come across the
cache manager functionality.

My end goal is to query the next hop for a specific IP address. So
basically what nl-route-get is providing.

Is it possible to query the cache rather than send a netlink message each
time I want to query routing information.

I can imagine that keeping the cache up to date is straight forward
however I don't see how you use the cache to get the
routing information rather than sending a nl message.

I have the nl message sending code working but would it be possible to use
a cache/manager implementation.

Are there any examples of what I am trying to do or did I misunderstand
how the cache can be used.

Thanks,

Tom
