How do I make child thread exit when main thread exit?

void forloop2()
{
    int i = 0;
    while(TRUE)
    {
        printf("forloop2\n");
    }
}

int main() {
    GThread          *Thread1;
    GtkWidget *window;
    g_thread_init(NULL);
    gdk_threads_init();
    gdk_threads_enter ();
    Thread1 = g_thread_create((GThreadFunc)forloop2, NULL, TRUE, NULL);
    gtk_init(NULL, NULL);
    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    gtk_widget_show_all (window);
    gtk_main();
    g_thread_join(Thread1);
    gdk_threads_leave ();
}

When I close the window, how to make Thread1 also exit?

Clear some condition in main that the loop in forloop2() checks on each iteration. When you want to exit from main, set that condition, then call g_thread_join() on Thread1. Since forloop2() checks when it sees that condition, it will exit, causing it to join, and main will proceed to exit.
