#include <X11/extensions/dmxext.h>
Bool DMXRemoveScreen(Display *dpy,
int screen);
DMXRemoveScreen() detaches the back-end screen from the Xdmx(1) server.
DMXRemoveScreen() returns True on success, and False if there were protocol errors, if the -addremovescreens command-line option was not specified on the Xdmx(1) command line, if the value of screen is out of range, or if the back-end screen specified by screen has already been detached.
