Signal prototypes

[Gabriele Greco <gabriele greco darts it>]

Given that different signals may have different prototypes:

"clicked": void (*)(GtkWidget *, void *)
"keypress": gboolean (*)(GtkWidget *, GdkEvent *, void *)
"delete_event": gboolean (*)(GtkWidget *, void *)
[...]

There is a way, from the signal name, to find in ADVANCE what kind of 
prototype the signal will expect?
