XSetEventQueueOwner(3) XLIB FUNCTIONS XSetEventQueueOwner(3)

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.
