passing a struct using extern C in a .dll c ++

Navigation

I have a function that comes from a .lib that returns me a struct 

tabela GSTV(vector<double> inpA, vector<double> inpB);

This struct is defined as follows: 

struct tabela {

    vector<int> Z;
    vector<double> F;
    vector<double> S;
    vector<double> Y;


};

But I'm turning this .lib into a .dll with extern "C"

When I have a vector I usually do: 

vector<int> GSTV(vector<double> inpA, vector<double> inpB);

become 

extern "C" MINHADLL_API void GSTV( vector<double> inpA, vector<double> inpB, vector<int> &GSTV_ans);

And so by the argument I generate my vector, however for a struct this is not working.

It seems like I just needed to declare a extern "C" of struct in the header of .dll also: 

extern "C" struct tabela;

In this way I understand that it converts the struct of the original .lib and works correctly the code.
