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.
