Your usage of GError is wrong. Please read the API documentation on it
again. The (probably) correct code is:


int
main (int   argc,
      char *argv[])
{
  guchar    *v;
  GdkPixbuf *pixbuf;
  GError    *error = NULL;

  g_type_init ();

  pixbuf = gdk_pixbuf_new_from_file ("image.jpg", error);
  
  if (pixbuf)
    v = gdk_pixbuf_get_pixels (pixbuf);
  else
    /* handle error here */;

  return 0;
}
