xenial (3) XSetEventQueueOwner.3.gz

NAME

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

SYNTAX

               #include <X11/Xlib-xcb.h>

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

ARGUMENTS

       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.

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

DESCRIPTION

       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 responses.
