passing array from Fortran to C++

[jw]

I would like to pass an array of structures from Fortran to C++. The C++ routine will populate the array of structures and return the values to my Fortran routine.

My Fortran code has the variable defined as:
RECORD/MY_STRUCT/ MY_ARRAY[100]

- How do I pass my "MY_ARRAY" to the C++ routine?
- How is MY_ARRAY defined in the C++ routine?

You could start by reading about iso_c_binding. The C++ function would have to be declared extern "C" as there is no portable way to deal with C++ name mangling.
