Regarding user data for wl_client.

[박성진]

Dear all and nicesj,
I push a patch to add get/set user data for wl_client.
If it does make sense, I think it'll be merged into the repository after getting reviewed.

Thanks and regards, 
Sung-Jin Park

As Pekka said they are missing as of now, however there is a workaround: have a

struct my_client {
  wl_listener destroy_listener;
  ...
};

and set the listener on the wl_client with
wl_client_add_destroy_listener(wl_client,
&my_client.destroy_listener), you can then retrieve the my_client from
the wl_client by doing

struct wl_listener *l = wl_client_get_destroy_listener(wl_client, ...);
struct my_client *c = container_of(l, struct my_client, destroy_listener);
