to pass a pointer, to a pointer, to a structure. do you mean like
CODE
void assign(double **dpp);

int main()
{
  double dbl;  //var
  double *p2dbl; //Pointer to var
  dbl = 0;
  p2dbl = &dbl;
  assign(&p2sbl);
  cout << "dbl: " << dbl << " *p2dbl: " << *p2dbl << "\n";
}
void assign (double **dpp)
{
     **dpp = 0.1;
     return;
}
