NOTA :
gpointer is typedef'd from (void *). You
do not need to declare data as a gpointer *.

Wouch... This lwindow is <i>local</i> to xmark_destroy(),
so setting it to NULL is useless.
It is not the lwindow you defined in markx (and BTW, the
markx() lwindow is local to markx() too - you cannot
access it ouside of its scope).
I suppose you want to do:
GtkWidget *global_lwindow = NULL;
void xmark_destroyed(GtkWidget *w, GdkEvent *e, gpointer data)
{
/* assuming the destroyed handler may be applied to another */
/* widget, so let's test it */
if (w == global_lwindow)
{
gtk_widget_destroy(global_lwindow);
global_lwindow = NULL;
}
}
void xmark()
{
...
if (global_lwindow != NULL)
{
gtk_widget_show(global_lwindow);
return;
}
/* your init */
global_window = ...
...
}
