+ (* This specifies an opaque pointer that is passed through
+ * untouched. Only non-daemon functions are supported.
+ *
+ * Pointer ("foo *", "bar") translates to "foo *bar" in the
+ * C API. The pointer ("bar") cannot be NULL.
+ *
+ * This is less well supported in other language bindings:
+ * if the pointer type is known then we may be able to produce
+ * a suitable binding, otherwise this is translated into a 64
+ * bit int.
+ *
+ * Functions with this parameter type are not supported at all
+ * in guestfish (the function must be declared "NotInFish" else
+ * you will get an error). Also the function cannot contain
+ * tests, although we should fix this in future.
