Here is a C code that I have tried to modify a bit in order to compile it in my C++ application.
When I compile I get this error message:

1>  All outputs are up-to-date.
1>AdvanceAdapter.obj : error LNK2019: unresolved external symbol __imp__getnameinfo@28 referenced in function "char * __cdecl ip6tos(struct sockaddr *,char *,int)" (?ip6tos@@YAPADPAUsockaddr@@PADH@Z)
1>...\Visual Studio 2010\Projects\Final\Debug\Final.exe : fatal error LNK1120: 1 unresolved externals

I would appreciate any comment
