If you mean the overall GSimpleAsyncResult behaviour; I guess the
reference is still the GLib/GIO API documentation:
http://developer.gnome.org/gio/unstable/GSimpleAsyncResult.html

But note that for new code, GTask is the new better and cleaner
GSimpleAsyncResult replacement:
http://developer.gnome.org/gio/unstable/GTask.html

There's no manual or tutorial just talking about async GIO functions,
AFAIK, I guess you just end up getting used to it...
