Field Documentation

RKH_PPRO_T prepro

Points to event preprocessor.

Aditionally, by means of single inheritance in C it could be used as state's abstract data. Aditionally, implementing the single inheritance in C is very simply by literally embedding the base type, RKH_PPRO_T in this case, as the first member of the derived structure.

This argument is optional, thus it could be declared as NULL.

Example:

static
RKH_SIG_T
preprocessor(RKH_EVT_T *pe)
{
   ...
}

typedef struct
{
   RKH_PPRO_T prepro;  // extend the RKH_PPRO_T class
   unsigned min:4;
   unsigned max:4;
   char *buff;
} SDATA_T;

static const SDATA_T option = {preprocessor, 4, 8, token1};

RKH_CREATE_BASIC_STATE(S111, set_x_1,
                      NULL, &S11, preprocessor);
RKH_CREATE_BASIC_STATE(S22, set_x_4,
                      NULL, &S2, (RKH_PPRO_T*)&option);
