I'm doing a C# project and I want to call next_permutation from the algorithm library in C++. I found the way to call c++ functions in c# but i dont know how to get vectors from c++ and use it in c# (cause next_permutation require a int vector...)

this is what I'm trying at the moment:

extern void NextPermutation(vector<int>& permutation) 
{
    next_permutation (permutation.begin(),permutation.end()); 
}

[DllImport("PEDLL.dll", CallingConvention = CallingConvention.Cdecl)]
        private static extern void NextPermutation(IntPtr test);
