[Xcb] Asking for help with xcb_wait_for_event function.

[John Found]

Hello.

I am not so sure, here is the right place to ask for support, 
but as long as I didn't found another...

Currently I am writing assembly language library with GUI toolkit. 
The Linux port uses XLib, but I want to try with XCB. The branch goes ok, but 
there is one problem, I can't find solution for.

The main thread of the program looks following way:

mainloop:
	ProcessSystemEvents;
	run_user_OnIdle_handler;
	WaitForSystemEvent;
loop_to_mainloop;

ProcessSystemEvents exits when the event queue is empty.
The user OnIdle handler must be executed only once per cicle.
WaitForEvent - simply put the thread in sleep until some event appears.

I am using xcb_poll_for_event in ProcessSystemEvents and xcb_wait_for_event
in WaitForSystemEvent. This way, as long as the xcb_wait_for_event removes 
the first event from the queue, I have to make very dirty hacks in order to
process it - now I am using global variable where to store the pointer returned 
from xcb_wait_for_event.

So, the question is: How to make xcb_wait_for_event to not remove the event from
the event queue, but symply to wait until event apears in the queue?

Best regards.
