Detailed Description

This file describes the interface to the client-side libdmx.a library. All DMX-aware client-side applications should include this file.

Enumeration Type Documentation

enum DMXInputEnum
 

Enumeration for the #inputType field in the DMXInputAttributes structure.

Function Documentation

Bool DMXAddBackendInput (  Display *  dpy,
int  screen,
int  sendsCore,
int *  newId
) 
 

Add backend input (a helper function that calls DMXAddInput).

Bool DMXAddConsoleInput (  Display *  dpy,
const char *  name,
int  sendsCore,
int *  newId
) 
 

Add console input (a helper function that calls DMXAddInput).

Bool DMXAddInput (  Display *  dpy,
unsigned int  mask,
DMXInputAttributes *  attr,
int *  id
) 
 

Add input.

Bool DMXAddScreen (  Display *  dpy,
const char *  displayName,
unsigned int  mask,
DMXScreenAttributes *  attr,
int *  screen
) 
 

Add a screen.

int DMXChangeDesktopAttributes (  Display *  dpy,
unsigned int  mask,
DMXDesktopAttributes *  attr
) 
 

Change the global bounding box and origin offset.

Available in DMX Protocol Version 2.0

int DMXChangeScreensAttributes (  Display *  dpy,
int  screen_count,
int *  screens,
int  mask_count,
unsigned int *  masks,
DMXScreenAttributes *  attrs,
int *  error_screen
) 
 

Change geometries and positions of the DMX screen and root windows on the back-end X server.

Bool DMXForceWindowCreation (  Display *  dpy,
Window  window
) 
 

The creation of the specified window will be forced.

Available in DMX Protocol Version 1.2 Reply added in DMX Protocol Version 2.0

Bool DMXGetDesktopAttributes (  Display *  dpy,
DMXDesktopAttributes *  attr
) 
 

If the DMXGetDesktopAttributes protocol request returns information correctly, the information will be placed in attr, and True will be returned. Otherwise, False will be returned.

Available in DMX Protocol Version 2.0

Bool DMXGetInputAttributes (  Display *  dpy,
int  id,
DMXInputAttributes *  inf
) 
 

If the DMXGetInputAttributes protocol request returns information about the input device with the specified id, information about the input device will be placed in inf, and True will be returned. Otherwise, False will be returned.

Available in DMX Protocol Version 1.1

Bool DMXGetInputCount (  Display *  dpy,
int *  input_count
) 
 

If the DMXGetInputCount protocol request returns the input count, the value will be placed in input_count, and True will be returned. Otherwise, False will be returned.

Available in DMX Protocol Version 1.1

Bool DMXGetScreenAttributes (  Display *  dpy,
int  physical_screen,
DMXScreenAttributes *  attr
) 
 

If the DMXGetScreenAttributes protocol request returns information for the specified physical_screen, information about the screen will be placed in attr, and True will be returned. Otherwise, False will be returned.

Available in DMX Protocol Version 1.0; Modified in Version 2.0

Bool DMXGetScreenCount (  Display *  dpy,
int *  screen_count
) 
 

If the DMXGetScreenCount protocol request returns the screen count, the value will be placed in screen_count, and True will be returned. Otherwise, False will be returned.

Available in DMX Protocol Version 1.0

Bool DMXGetWindowAttributes (  Display *  dpy,
Window  window,
int *  screen_count,
int  available_count,
DMXWindowAttributes *  inf
) 
 

If the DMXGetWindowAttributes protocol request returns information about the specified window, the number of screens for which information is available will be returned in screen_count and information about the first available_count of those screens will be placed in inf. Because this call transports a great deal of information over the wire, please call DMXGetScreenCount first, and make sure inf is that large.

Note that if the specified window has not yet been mapped when DMXGetWindowAttributes is called, then a subsequent XMapWindow call might be buffered in xlib while requests directly to the back-end X servers are processed. This race condition can be solved by calling DMXSync before talking directly to the back-end X servers.

Available in DMX Protocol Version 1.0, but not working correctly until DMX Protocol Version 1.4

_XFUNCPROTOBEGIN Bool DMXQueryExtension (  Display *  dpy,
int *  event_basep,
int *  error_basep
) 
 

If the server has the DMX extension, the event and error bases will be placed in event_basep and error_basep, and True will be returned. Otherwise, False will be returned.

Available in DMX Protocol Version 1.0

Bool DMXQueryVersion (  Display *  dpy,
int *  majorVersion,
int *  minorVersion,
int *  patchVersion
) 
 

If the DMXQueryVersion protocol request returns version information from the server, majorVersion, minorVersion, and patchVersion are filled in with the appropriate information and True is returned. Otherwise, False will be returned.

Available in DMX Protocol Version 1.0

Bool DMXRemoveInput (  Display *  dpy,
int  id
) 
 

Remove an input.

Bool DMXRemoveScreen (  Display *  dpy,
int  screen
) 
 

Remove a screen.

Bool DMXSync (  Display *  dpy  ) 
 

Flush all pending dmxSync requests in DMX server.

Available in DMX Protocol Version 1.5
