Just use a structure with the two arguments and pass a pointer to such a
structure.

  typedef struct
  {
    int foo;
    char *bar;
  } myargs;

  myargs args_for_this_widget;

  GtkItemFactoryEntry items[] = {
  {"/File/_Open","<alt>O", abrir , &args_for_this_widget, NULL}
  };


  void abrir(GtkWiget *widget, gpointer data)
  {
    myargs *args = (myargs *)data;
    char *filename;

    assert(myargs != NULL);

    filename = myargs->bar;

  }
