Fortran 2003 Features
Interoperability with C
Chapter 12254
Interoperability with C
HP-UX fortran compiler supports the fortran 2003 standard mechanism to allow communication between
fortran code and C code. The intrinsic module ISO_C_BINDING contains named constants that hold kind
type parameter values for intrinsic types for interoperability between C and Fortran. Interoperability of
Intrinsic types, C pointers, Derived types, Variables, global data and procedures are supported in the HP-UX
fortran compiler.
Currently, the C function pointers are not interoperable with Fortran.
