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;
}
