DMXRemoveInput – detach an input Synopsis #include <X11/extensions/dmxext.h> Bool DMXRemoveInput(Display *dpy, int id); Description DMXRemoveInput() 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 Value DMXRemoveInput() returns True unless there…
DMXQueryVersion – determine DMX extension version Synopsis #include <X11/extensions/dmxext.h> Bool DMXQueryVersion(Display *dpy, int *major_version, int *minor_version, int *patch_version); Description DMXQueryVersion() 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,…
DMXQueryExtension – determine if DMX is available Synopsis #include <X11/extensions/dmxext.h> Bool DMXQueryExtension(Display *dpy, int *event_basep, int *error_basep); Description DMXQueryExtension() determines if the DMX protocol extension is available. It will be available if the server is an Xdmx(1) server. Return Value If the DMX protocol extension is available, event_basep and error_basep will be set to the…
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); Description When 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…
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….
DMXGetScreenAttributes – determine back-end screen attributes Synopsis #include <X11/extensions/dmxext.h> Bool DMXGetScreenAttributes(Display *dpy, int screen, DMXScreenAttributes *attr); Description DMXGetScreenAttributes() returns the attributes for the single DMX screen specified in screen. The DMXScreenAttributes structure is: typedef struct { char *displayName; int logicalScreen; unsigned int screenWindowWidth; unsigned int screenWindowHeight; int screenWindowXoffset; int screenWindowYoffset; unsigned int rootWindowWidth; unsigned int…
DMXGetInputCount – determine number of input devices Synopsis #include <X11/extensions/dmxext.h> Bool DMXGetInputCount(Display *dpy, int *input_count); Description DMXGetInputCount() returns the number of input devices connected to the Xdmx(1) server in input_count. This number is the same as that returned by XListInputDevices(3), but is available even when the XInput extension is not supported. Return Value DMXGetInputCount() returns…
DMXGetInputAttributes – determine input device attributes Synopsis #include <X11/extensions/dmxext.h> Bool DMXGetInputAttributes(Display *dpy, int id, DMXInputAttributes *attr); Description DMXGetInputAttributes() 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…
DMXGetDesktopAttributes – determine global bounding box Synopsis #include <X11/extensions/dmxext.h> Bool DMXGetDesktopAttributes(Display *dpy, DMXDesktopAttributes *attr); Description DMXGetDesktopAttributes() returns information about the desktop in DMXDesktopAttributes: typedef struct { unsigned int width; unsigned int height; int shiftX; int shiftY; } DMXDesktopAttributes; The size of the global bounding box is given in width, and height. The shiftX and shiftY…
DMXForceWindowCreation – force immediate back-end window creation Synopsis #include <X11/extensions/dmxext.h> Bool DMXForceWindowCreation(Display *dpy, Window window); Description When using the lazy window creation optimization, windows are not created on the back-end X servers until they are required. DMXForceWindowCreation() forces the immediate creation of the window requested. Return Value DMXForceWindowCreation() returns True unless there is a protocol…
DMXChangeScreensAttributes – change back-end screen attributes Synopsis #include <X11/extensions/dmxext.h> int DMXChangeScreensAttributes(Display *dpy, int screen_count, int *screens, int mask_count, unsigned int *masks, DMXScreenAttributes *attr, int *error_screen); Description DMXChangeScreensAttributes() changes the geometries and positions of the DMX screen and DMX root windows on the back-end X servers. screen_count specifies the number of screens to be changed. For…
DMXChangeDesktopAttributes – change global bounding box Synopsis #include <X11/extensions/dmxext.h> int DMXChangeDesktopAttributes(Display *dpy, unsigned int mask, DMXDesktopAttributes *attr); Description DMXChangeDesktopAttributes() resizes the bounding box of the whole screen when using the Xinerama extension. Otherwise, it has no effect on the screen layout. An attribute mask is placed in mask and the attributes to change are placed…
