I am attempting to pass a C++ array of pointers into a Fortran subroutine.
The C++ array is of a structure, which exactly conforms to a Fortran derived type.
So in C++ I have pArray* c_arr[DIM1][DIM2];
Then I call a Fortran sub, passing in the C++ array of pointers like fortsub(c_arr[0][0])
In Fortran I have Subroutine fortsub (fort_arr) where I need fort_arr to be a container for the array of pointers.
I currently do not know how to make this work, I have something like:
Type (type1), Dimension(2,*), Target :: fort_arr where type1 is the same type as pArray.
Basically, my problem is I don't know how to pass a double dimensioned array of C++ structure pointers into a Fortran subroutine.
I know that he concept of "array of pointers" does not exist in Fortran and the way you have to do it is have an array of derived type with a pointer component, but I cannot seem to get the data passing on the argument list correct.
Anyone have some advice, perhaps with a specific example? I would appreciate it greatly. Thanks.
