The problem is that the Fortran standard supports those semantics only for a Fortran pointer, not for a C pointer. I will take the liberty to interpret the standard words "any pointer associated with the dummy shall become associated with the actual" to apply to C pointers as well. Otherwise TYPE(C_PTR) is useless. Of course one can modify the object it points to through the pointer, in C. What else is there? Maybe the standard is not super clear about it, but that's a different issue. I believe the intent has been that the C standard describes that, no need to repeat in the Fortran one. Best, Aleks
