Idle Functions

What if you have a function which you want to be called when nothing else is happening ?

guint g_idle_add( GSourceFunc function,
                  gpointer    data );

This causes GTK to call the specified function whenever nothing else is happening.

void g_source_remove( guint tag );

I won't explain the meaning of the arguments as they follow very much like the ones above. The function pointed to by the first argument to g_idle_add will be called whenever the opportunity arises. As with the others, returning FALSE will stop the idle function from being called.
