XEventsQueued equivalent in xcb

问题

I have read 'Need for XEventsQueued(display, QueuedAfterReading) in XCB' but the answer specifies a function (xcb_poll_for_queued_event) that modifies the internal event queue. I need a function that is exactly the equivalent of XEventsQueued(display, QueuedAfterReading).

Modifying the event queue breaks the code I'm currently writing if done where XEventsQueued would be used.

What is the equivalent function or block of code in xcb?
