DMXGetScreenCount(3)	    Library Functions Manual	    DMXGetScreenCount(3)

NAME
     DMXGetScreenCount - determine number of back-end screens

SYNOPSIS
     #include <X11/extensions/dmxext.h>

     Bool DMXGetScreenCount(Display *dpy,
			    int *screen_count);

DESCRIPTION
     DMXGetScreenCount()  returns  the number of back-end screens that a Xdmx(1)
     server controls.  Since a DMX screen usually fills	 all  of  the  available
     area on a back-end server, there is usually a one-to-one correspondence be-
     tween  DMX screens and backend servers.  However, it is also possible for a
     DMX screen to cover only part of the available area on a  back-end	 server,
     and  for more than one DMX screens to occupy different parts of the visible
     area on the same back-end server.

     A DMX screen may be managed as a regular X screen in the Xdmx(1) server  or
     may be joined with other DMX screens using Xinerama.

RETURN VALUE
     DMXGetScreenCount()  sets	screen_count  and returns True unless there is a
     protocol error.

NOTES
     If Xinerama is active, only one logical screen will be available to clients
     of the Xdmx(1) server.  However, this call will accurately reflect the num-
     ber of composite back-end screens that the Xdmx(1) server is using.
