DMXSync – flush protocol requests between Xdmx and back-end X servers Synopsis#include <X11/extensions/dmxext.h> Bool DMXSync(Display *dpy);DescriptionDMXSync() flushes all pending protocol requests between the Xdmx(1) server and each back-end X server. It is used by clients that talk directly to back-end X servers to ensure that all pending Xdmx(1) requests have reached all back-end servers and…
DMXRemoveScreen – detach a back-end screen Synopsis#include <X11/extensions/dmxext.h> Bool DMXRemoveScreen(Display *dpy, int screen);DescriptionDMXRemoveScreen() detaches the back-end screen from the Xdmx(1) server. Return ValueDMXRemoveScreen() returns True on success, and False if there were protocol errors, if the -addremovescreens command-line option was not specified on the Xdmx(1) command line, if the value of screen is out of…
DMXRemoveInput – detach an input Synopsis#include <X11/extensions/dmxext.h> Bool DMXRemoveInput(Display *dpy, int id);DescriptionDMXRemoveInput() detaches the input device with id, and all associated inputs (e.g., if the id is a backend mouse, and a keyboard is also attached to the backend, then both devices will be detached). Return ValueDMXRemoveInput() returns True unless there is a protocol error….
DMXQueryVersion – determine DMX extension version Synopsis#include <X11/extensions/dmxext.h> Bool DMXQueryVersion(Display *dpy, int *major_version, int *minor_version, int *patch_version);DescriptionDMXQueryVersion() returns version information about the DMX protocol extension. Any incompatible changes to the protocol will be indicated by a change in major_version. Small, upward-compatible changes will be indicated by a change in minor_version. In general, patch_version is for…
DMXQueryExtension – determine if DMX is available Synopsis#include <X11/extensions/dmxext.h> Bool DMXQueryExtension(Display *dpy, int *event_basep, int *error_basep);DescriptionDMXQueryExtension() determines if the DMX protocol extension is available.

DMXGetWindowAttributes – determine back-end window attributes Synopsis#include <X11/extensions/dmxext.h> Bool DMXGetWindowAttributes(Display *dpy, Window window, int *screen_count, int available_count, DMXWindowAttributes *attr);DescriptionWhen calling DMXGetWindowAttributes(), window specifies the window ID of a window on the Xdmx(1) server and available_count specifies the length of attr. The number of screens for which information is available will be returned in screen_count and…
DMXGetScreenCount – determine number of back-end screens Synopsis#include <X11/extensions/dmxext.h> Bool DMXGetScreenCount(Display *dpy, int *screen_count);DescriptionDMXGetScreenCount() 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…
DMXGetScreenAttributes – determine back-end screen attributes Synopsis#include <X11/extensions/dmxext.h> Bool DMXGetScreenAttributes(Display *dpy, int screen, DMXScreenAttributes *attr);DescriptionDMXGetScreenAttributes() returns the attributes for the single DMX screen specified in screen.

This number is the same as that returned by XListInputDevices(3), but is available even when the XInput extension is not supported. Return ValueDMXGetInputCount() returns True unless there is…
DMXGetInputAttributes – determine input device attributes Synopsis#include <X11/extensions/dmxext.h> Bool DMXGetInputAttributes(Display *dpy, int id, DMXInputAttributes *attr);DescriptionDMXGetInputAttributes() returns information about the input device specified with id. This information cannot be obtained from the XListInputDeivices(3) call. id is the same as that used by the XListInputDevices(3) call, and must be in the range 0 to one less than…
