I am working on a library designed to work with fortran allocated memory in C.

I want to add support for the derived types. For that I need an equivalent type hardcoded in C, that is what a library requires. What is the best way to automate it?

Example:

  type, bind(c) :: coordinatesfloat
    real(c_float) :: x
    real(c_float) :: y
  end type coordinatesfloat

to

typedef struct coordinatesfloat {
  float x;
  float y;
} coordinatesfloat;

I have seen tools like f2c, but it feels too much to introduce a dependency just for type "conversion". Is writing a script a better idea? How would an interface for registering a type look like?
