DMXForceWindowCreation – force immediate back-end window creation Synopsis#include <X11/extensions/dmxext.h> Bool DMXForceWindowCreation(Display *dpy, Window window);DescriptionWhen using the lazy window creation optimization, windows are not created on the back-end X servers until they are required. DMXForceWindowCreation() forces the immediate creation of the window requested. Return ValueDMXForceWindowCreation() returns True unless there is a protocol error. DMXForceWindwoCreation() can generate…
