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