XSetEventQueueOwner(3) XLIB FUNCTIONS XSetEventQueueOwner(3) NAME XSetEventQueueOwner - set event queue owner on a shared Xlib/XCB con- nection 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-han- dling 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 func- tions. 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 com- patibility with legacy Xlib clients. Clients can call XSetEventQueue- Owner immediately after XOpenDisplay to let XCB own the event queue in- stead. Clients may not call XSetEventQueueOwner at any other time, as this will potentially lose responses.
