[fpc-pascal] data types of GSL

[Ramom Flores d'as Seixas]

In order to use some functions of the gsl (GNU Scientific Library) it is 
necessary to translate some data types from C to pascal. But my knowledge of 
C is tiny. So I would thanks if somebody translate the following piece of 
code:


struct gsl_function_struct
{
  double (* function) (double x, void * params);
  void * params;
};




Thanks
Ramom
