--- Comment #5 from Thomas Koenig <tkoenig at gcc dot gnu.org> --- Hi Paul, > I am sure that the array part is OK. Otherwise, why have a type code for > strings? It 18.5 The source file ISO_Fortran_binding.h 18.5.1 Summary of contents The source file ISO_Fortran_binding.h shall contain the C structure definitions, typedef declarations, macro definitions, and function prototypes specified in 18.5.2 to 18.5.5. The definitions and declarations in ISO_- Fortran_binding.h can be used by a C function to interpret and manipulate a C descriptor. These provide a means to specify a C prototype that interoperates with a Fortran interface that has a non-interoperable dummy variable (18.3.6). And the length of the character should be passed as element_len in the various CFI_* functions. > I guess scalars can be handled by passing to an assumed rank array. An array of character*1 is interoperable, yes. Regards Thomas
