c - Function pointer array, passing values defined in array -

i'm trying define array of function pointers, each function contains int parameter. i'm trying set value of int parameter in array declaration

so have timed_task struct, hold function pointer , value want pass

typedef struct {    void (*proc)(int);      int delaymsec;      } timed_task; 

then have array of timed_tasks this

static const timed_task attractsequence[] = {     { lightson, 1000 },     { lightsoff, 500 },     { endsequence, 0 } }; 

and i'd call each of functions in turn, passing delay value each function. expect have wrong syntax (i'm still learning c). seemingly don't hit lightson() routine @ all

void loop() // it's arduino project :) {   attractsequence[sequence];   sequence++; }  void lightson(int pause) {   // not hit routine reason?   serial.print("lights on");    serial.print(pause); }  void lightsoff(int pause) {   serial.print("lights off");   serial.print(pause); } 

it's entirely possible i'm taking wrong approach here, can see i'm trying achieve. advice welcome!

if want go through each item of attractsequence once, can use:

void loop() {    int count = sizeof(attractsequence)/sizeof(attractsequence[0]);    (int = 0; < count; ++i )    {      attractsequence[i].proc(attractsequence[i].delaymsec);    } }
