Use of function pointers in Redis

Declare the function pointer in the header file first

typedef void Functionpoint (int i, int j);

struct dataevent

{

Functionpoint *pproc;

int num;

};

declaring a function that invokes a function pointer

void aeevents (struct dataevent *data);

implementing Aeevents in. c Files (dataevent *data)

void Aeevents (Dataevent *data) {     Data->pproc (9, 10);}

Call the above function pointer in the main function

static int Aerealfunc (int i, int j) {return i+j;}

void Main ()

{

struct dataevent param;

Param.pproc = Aerealfunc;
aeevents (&param);

}
