Detailed Description

FORTRAN file data input and output functions.

Since

November 2002

The functions in this group serve mainly to read FORTRAN binary data files into C++ variables or arrays. There may be also writing functions and functions for FORTRAN formatted ASCII files added. This module makes extensive use of the I/O byte swapping facility.

I/O is most easily accomplished by using the overloaded versions of the I/O input and output operators. For I/O of complex types specialized versions are presented in complexio.h. These operators are placed in the global namespace.

Test of I/O-routines

The I/O routines where testet on 20/11/2002. The test code may be found in tests/fortraniotest.cc, which is documented in TEST: Fortran I/O and byte swapping., and in tests/fortranF77.f, which is the Fortran 77 part of the test module. The Fortran part was compiled and run on two systems:

1. AIX geo31 3 4 002030455700 (Motorola CPU)
2. Linux geo19 2.4.4-64GB-SMP #1 SMP i686 unknown (Intel CPU)

The C++ part of the test was only compiled on the Linux machine. The test was successfully passed for magic numbers, I/O and byteswapping I/O (from/to Fortran77/C++ and Motorola/Intel) performed with the following C++ types:

1. int
2. long int
3. long long int
4. float
5. double
6. complex<float>
7. complex<double>
