How to pass a user-defined type to C++

[lihua325]

Hi,

In my fortran, I have a type called velocity:

type velocity
real*8:: x
real*8:: y
end type velocity

I also have

type(velocity), dimension(:,:), allocatable::U

Now I want to pass this U to a C++ function, can anyone give me an example to show me how to do it?

thanks a lot.
