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.
