Re: gobjects, glists and arrays beginners question

Hi!
I think, that better way is (this is example only) :

typedef struct _Machine Machine;

struct _Machine {
  gint machine_number;
  gchar *machine_name;
  gchar *model;
  gchar *operator;
  /* ... */
};

Machine *machine_new(gint machine_number,
                                      const gchar *machine_name,
                                      const gchar *model,
                                      const gchar *operator)
{
  Machine *machine;

  g_return_val_if_fail(machine_number > 0, NULL);
  g_return_val_if_fail(machine_name != NULL, NULL);
  g_return_val_if_fail(model != NULL, NULL);
  g_return_val_if_fail(operator != NULL, NULL);

  machine = g_new(Machine, 1);
  machine->machine_number = machine_number;
  machine->machine_name = g_strdup(machine_name);
  machine->model = g_strdup(model);
  machine->operator = g_strdup(operator);
  /* ... */

  return machine;
}                                     
void machine_free(Machine *machine)
{
  g_return_if_fail(machine != NULL);

  /* ... */
  g_free(machine->machine_name);
  g_free(machine->model);
  g_free(machine->operator);
  g_free(machine);
}

For store Machine's you can use one of GLib containers.
