DMXSync - Man Page

#include <X11/extensions/dmxext.h>

Bool DMXSync(Display *dpy);

DMXSync() flushes all pending protocol requests between the Xdmx(1) server and each back-end X server.  It is used by clients that talk directly to back-end X servers to ensure that all pending Xdmx(1) requests have reached all back-end servers and have been processed by those servers.

DMXSync() returns True unless there is a protocol error.
