Using XL C/C++ with Fortran

With XL C/C++, you can call functions written in Fortran from your C and C++ programs. This section discusses some programming considerations for calling Fortran code in the following areas:

• Identifiers
• Corresponding data types
• Character and aggregate data
• Function calls and parameter passing
• Pointers to functions

In topic Sample program: C/C++ calling Fortran, an example of a C program that calls a Fortran subroutine is provided.
