       XSetEventQueueOwner - set event queue owner on a shared Xlib/XCB connection


	       #include <X11/Xlib-xcb.h>

       void XSetEventQueueOwner(Display *dpy, enum XEventQueueOwner owner);

       dpy	 Specifies the connection to the X server.

       owner	 Specifies the event queue ownership:

		 XlibOwnsEventQueue (default)
			Xlib  owns  the  event queue.  Use the Xlib event-handling functions.  Do
			not call the XCB event-handling functions.

			XCB owns the event queue.  Use the XCB event-handling functions.  Do  not
			call the Xlib event-handling functions.

       While  a  client using Xlib/XCB can issue requests and handle their replies or errors with
       either Xlib or XCB, only one can own and handle the event queue.  By  default,  Xlib  must
       own  the  event	queue,	for  compatibility  with  legacy  Xlib clients.  Clients can call
       XSetEventQueueOwner immediately after XOpenDisplay to let XCB own the event queue instead.
       Clients	may not call XSetEventQueueOwner at any other time, as this will potentially lose
