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 cor-
       respondence between 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  dif-
       ferent 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  re-
       flect  the number of composite back-end screens that the	Xdmx(1)	server
       is using.
