How does the Fortran interface differ from the C interface?
It provides all the functionality of the C interface. The Fortran interface uses Fortran conventions for array indices, subscript order, and strings. There is no difference in the on-disk format for data written from the different language interfaces. Data written by a C language program may be read from a Fortran program and vice-versa. The Fortran-90 interface is much smaller than the FORTRAN 77 interface as a result of using optional arguments and overloaded functions wherever possible.
