how to i get the arrow-buttons moving?

[Gary Kline]

here are thee labels that show up when you use the gcc compile string.
how do I get the up- and -down arrows to point at the label and echo the
"label strings"?

#include <stdio.h>
#include <gtk/gtk.h>

  /*
     COMPILE WITH:

gcc -Wall -Wextra -g arrow.c -o arrow `pkg-config --cflags gtk+-3.0` 
`pkg-config --libs gtk+-3.0`

create_arrow_button (GtkArrowType arrow_type,
                     GtkShadowType shadow_type)
{
  GtkWidget *button;
  GtkWidget *arrow;

  button = gtk_button_new ();
  arrow = gtk_arrow_new (arrow_type, shadow_type);

  gtk_container_add (GTK_CONTAINER (button), arrow);

  gtk_widget_show (button);
  gtk_widget_show (arrow);

  return (button);
}

static void
button_clicked (__attribute__ ((unused)) GtkButton *button,
                gpointer   user_data)

  printf ("button %d clicked\n", GPOINTER_TO_INT (user_data));
