Searching for a network function...

[sever]

Hi folks,

I'm working in a daemon that needs to identify if a binded node (identified by an address, expressed in IPv6) belongs to an specific subnetwork.

For this issue, I suppose that I need a kind of "function" that takes both the addresses of the node and of the network...

Does this kind of function exist in the C/C++ GNU/Linux programming API... or should be written ad hoc?

In case of should written, I'll need some help...
