gtk_window_set_default_icon_name

["Jonathon Jongsma" <jonathon jongsma gmail com>]

I noticed that one of the recent Gnome Goals was regarding
theme-friendly icons (see http://live.gnome.org/GnomeGoals/AppIcon). 
They recommend using the function gtk_window_set_default_icon_name(). 
I don't see any equivalent to this in gtkmm.  Is there a different way
to do this in gtkmm or is it just not wrapped yet?

Also, is there an easy way to tell which GTK+ functions are not
wrapped yet (i.e. a script to run against the sources or something?)
