Yeah, you've convinced me. I don't like the name (and, by extension, don't
like the others) but it goes better with the current API. Let's go with
that.

Hi,
hm, that's a tricky one. Yes, the name wl_event_queue_roundtrip() is
confusing when out of context, but as the argument is a wl_event_queue,
that name is the logical and unfortunate result.
Another problem with wl_display_roundtrip_queue() is that it gets both
wl_display and wl_event_queue as arguments. Therefore the function
would need to check that the wl_event_queue indeed belongs to the given
wl_display. It's just a thing one can get wrong, and it has no benefits
that I see.
wl_display_roundtrip_queue() taking only wl_event_queue as an argument
would be strange, because the name implies a wl_display method.
(Up until this point, I would have agreed with Giulio and Jason...)
But, now I see, that we already have:
int wl_display_dispatch_queue(struct wl_display *display,
struct wl_event_queue *queue);
int wl_display_dispatch_queue_pending(struct wl_display *display,
struct wl_event_queue *queue);
int wl_display_prepare_read_queue(struct wl_display *display,
struct wl_event_queue *queue);
So there is precendent, that redundant arguments are ok, and
wl_display_roundtrip_queue() would indeed follow the existing scheme.
Btw. I do not see anywhere, where the libwayland-client code would be
checking that the wl_display and the wl_event_queue would actually be
related. Would be a good thing to add more checks to the public API
functions for that.
I think I would go with wl_display_roundtrip_queue() here. Would you
agree?

I didn't realize you could read it as "queue a roundtrip on a
wl_event". I think that the meaning is quite obvious once you know
that there is a wl_event_queue type in Wayland.

TBH I'd rather steer clear of that nomenclature, since the 'queue' in an
immediate request context implies delayed dispatch, rather than on a queue.

It's not my fault it's named wl_even_queue and therefore tne natural name
sounds like you're queueing a roundtrip on a wl_event object... That said,
you do have a point and it is a bad name. I just don't know what else to
call it.
