C++ passing an array pointer as a function argument

I'm trying to use pointers of arrays to use as arguments for a function which generates an array.

void generateArray(int *a[],  int *si){
  srand(time(0));
  for (int j=0;j<*si;j++)
       *a[j]=(0+rand()%9);
} //end generateArray;

int main() {
  const int size=5;
  int a[size];

  generateArray(&a, &size);

  return 0;
} //end main

But when I compile this this message appears:

cannot convert `int (*)[5]' to `int**' for argument `1' to `void generateArray(int**, int*)'
