Ah, I should have said that to make sense of this you also need to see:

http://efax-gtk.cvs.sourceforge.net/*checkout*/efax-gtk/efax-gtk/src/utils/io_watch.h
http://efax-gtk.cvs.sourceforge.net/*checkout*/efax-gtk/efax-gtk/src/utils/io_watch.cpp
which connects a file descriptor to the Glib main loop and
http://efax-gtk.cvs.sourceforge.net/*checkout*/efax-gtk/efax-gtk/src/utils/pipes.h
http://efax-gtk.cvs.sourceforge.net/*checkout*/efax-gtk/efax-gtk/src/utils/pipes.cpp
which wraps a unix anonymous pipe.
