 From C++ side it's necessary to declare and compile the function extern 
"C" and it must be exported from the resulting shared library (by 
__declspec(dllexport) or __attribute__ ((visibility ("default"))), 
depending on the platform).

For sure an experienced C++ programmer is able to do that easily. After 
that, the ball is on the Fortran side.
