Fortran & C - index

This page gives some of the useful tricks to know when combining C and Fortran. "Why bother?" you may ask. Both languages have nice features that can be profitably exploited. Standard C provides low-level control over many operations. Fortran is optimized for numeric calculation and there is a large collection of numeric libraries already available.

These pages only use Fortran77, which is still the predominant Fortran standard (and a subset of Fortran90). When a GNU g90, or some freely available, compiler becomes available then I will add more Fortran90 information. Also these pages use Standard C, which is a subset of "standard" C++, since Fortran is not object-oriented.

• Mixing calls to Fortran & C ... correctly handling how data & arguments are passed.
• Using C to allocate memory for Fortran
