Convert .Net ref (%) to native (&)

Question

How can I convert a C++/CLI int %tmp to native C++ int &tmp?

void test(int %tmp)
{
    // here I need int &tmp2 for another pure C++ function call
}

Answer 1

void your_function(int *);
void your_function2(int &);

void test(int %tmp)
{
    int tmp2;
    your_function(&tmp2);
    your_function2(tmp2);
    tmp=tmp2;
}
