I'm triying to write into an array which in turn is into a garray type.

I wrote the following function:

void write_table(t_tabwrit *x, t_symbol *name)
{
    t_garray *a;
    t_array *b;
    int size=0, i, yonset=0;
    t_float step=0., val=0.;  

    x->table_name = name;
  if (!(a = (t_garray *)pd_findbyclass(x->table_name, garray_class))) {
    if (*name->s_name)
      pd_error(x, "tabwrit: ERROR, %s: no such array", x->table_name->s_name);
            x->table_name=NULL;
  }

    b=(t_array *)garray_getarray_floatonly(a, &yonset, &size);
    step= 1. / (float)size;
   
    for(i=0; i < size; ++i) {
      *((t_float *)(b->a_vec + i + yonset))=val;
        val+=step;       
    }

    garray_redraw(a);
return;
}

But I get from the compiler the following error:
"error: dereferencing pointer to incomplete type"

I understand the maning of the error, but I've looked at the definition

of the array and garray types and I found no such "incomplete" type.

Any idea?

Or any other way to write floats to a garray vector?

Many thanks
