shouldn't gtk_main_iteration() return gboolean?

[Yasushi Shoji <yashi yashi com>]

hi,

could someone explain me why gtk_main_iteration() returns gint rather
than gboolean?

in cvs, gtkmain.c:gtk_main_iteration() is as follows:

> gint 
> gtk_main_iteration (void)
> {
>   GDK_THREADS_LEAVE ();
>   g_main_iteration (TRUE);
>   GDK_THREADS_ENTER ();
> 
>   if (main_loops)
>     return !g_main_is_running (main_loops->data);
>   else
>     return TRUE;
> }

this function returns TRUE or the value returned by
g_main_is_running() which returns gboolean as defined in glib/gmain.c:

> gboolean
> g_main_is_running (GMainLoop *loop)
> {
>   g_return_val_if_fail (loop != NULL, FALSE);
> 
>   return loop->is_running;
> }

Am I missing something?
