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
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 );
