Data description

Each parameter of a client problem is manipulated by DIET using the following structure:

typedef struct diet_arg_s diet_arg_t;
struct diet_arg_s{
  diet_data_desc_t desc;
  void            *value;
};
typedef diet_arg_t diet_data_t;

The second field is a pointer to the memory zone where the parameter data are stored. The first one consists of a complete DIET data description, which is better described by a figure than with C code, since it can be set and accessed through API functions. Figure 3.1 shows the data classification used in DIET. Every “class” inherits from the root “class” data, and could also be a parent of more detailed classes of data in future versions of DIET.
