Calling C++ from Fortran

[ivanpribec]

Is it not an option to make a wrapper C++ class that contains RNG things and use the pointer to it (opaque handle) from the Fortran side? (If that pointer is deleted manually, the destructor also takes care of the RNG things…?)

It’s possible but involves much more tedious wrapping. Here’s an earlier thread from this forum: Issues interfacing between C++ and Fortran - #4 by FortranFan

Also, I’m wondering if it is possible to catch exception in a general manner on the C++ side, and if necessary, return related messages to the Fortran side?

If you know a function may raise an exception you need to use the try-block to catch any exceptions, and convert them to “Fortran” error handling → integer status flag and an optional error message output arguments.
