Unfortunately this doesn't work. The handle (guestfs_h *) is wrapped inside a GType: typedef struct _GuestfsH { GObject parent; guestfs_h *h; } GuestfsH; I can now register this easily enough, but GObject won't automatically unpack that handle when it passes it to the other functions. ie. The other functions would receive a GuestfsH, instead of a guestfs_h *, and they won't know what to do with the former.
