In folder
Code:
C:\Program Files\Silverfrost\FTN95\demo\win32\visualcinteroperability2\vcproject1


File "vcproject1.cpp", line 81,
Code:
extern "C" DllExport void _FunctionArgumentsReference(int *i, double *x)
the type of *x should be changed to "float", which corresponds to "real" in FORTRAN. Otherwise, the program will not run as intended.

Comparison of FORTRAN and C/C++ datatypes:

Yes you are right, double would correspond to REAL*8, which is not used in this example. The example has been changed to float.
