c2v cannot process: void (**implementation)(void)

[finomeng]

hi team,
I want to wrap the headers for wayland-client.so
but seem c2v cannot process: **

int wl_proxy_add_listener(struct wl_proxy proxy, void (**implementation)(void), voiddata);

the file is /usr/include/wayland-client-core.h , on Ubuntu 24.04

log:

$ v translate wayland-client.h
wayland-client.v:571:63: error: unexpected token `(`, expecting `,`
  569 | fn wl_proxy_destroy(proxy &Wl_proxy)
  570 | 
  571 | fn wl_proxy_add_listener(proxy &Wl_proxy, implementation Void (**)(void), data voidptr) int
      |                                                               ^
  572 | 
  573 | fn wl_proxy_set_user_data(proxy &Wl_proxy, user_data voidptr)

Internal vfmt error while formatting file: /projects/_KodGraf_/kodgraf/wayland/h/wayland-client.v.

Thanks.

I got new finding,
if I use c2v wrapper waydland-client.h, there is no error happen. so I got confused.

tail of log:

c2v: translate_file() DONE

VVVV len=0
{}
 c2v translate_file() took   292 ms ; output .v file: wayland-client.v

it seems c2v wrapper is the same cmd with v translate wrapper
