DMXGetScreenCount(3X)                                                                  DMXGetScreenCount(3X)



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 one-toone
       one  correspondence  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 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 number of composite back-end screens that the Xdmx(1)
       server is using.
