It has to be. Look:

void
gdk_draw_arc (GdkDrawable *drawable,
              GdkGC       *gc,
              gint         filled,
              gint         x,
              gint         y,
              gint         width,
              gint         height,
              gint         angle1,
              gint         angle2)

  GdkWindowPrivate *drawable_private;
  GdkGCPrivate *gc_private;

  g_return_if_fail (drawable != NULL);
  g_return_if_fail (gc != NULL);

  drawable_private = (GdkWindowPrivate*) drawable;
  if (drawable_private->destroyed)
    return;
  gc_private = (GdkGCPrivate*) gc;

  if (width == -1)
    width = drawable_private->width;
  if (height == -1)
    height = drawable_private->height;

  if (filled)
    XFillArc (drawable_private->xdisplay, drawable_private->xwindow,
              gc_private->xgc, x, y, width, height, angle1, angle2);
  else
    XDrawArc (drawable_private->xdisplay, drawable_private->xwindow,
              gc_private->xgc, x, y, width, height, angle1, angle2);

}
