Detailed Description

Interface for DMX extension support. These routines are called by function in Xserver/Xext/dmx.c.

Function Documentation

int dmxAddInput (  DMXInputAttributesPtr  attr, int *  id )

Add an input with the specified attributes. If the input is added, the physical id is returned in deviceId.

int dmxAttachScreen (  int  idx, DMXScreenAttributesPtr  attr )

Reattach previously detached back-end screen.

int dmxDetachScreen (  int  idx  )

Detach back-end screen.

void dmxFlushPendingSyncs (  void   )

Flush pending syncs for all screens.

void dmxForceWindowCreation (  WindowPtr  pWindow  )

Make sure that dmxCreateAndRealizeWindow has been called for pWindow.

int dmxGetInputAttributes (  int  deviceId, DMXInputAttributesPtr  attr )

Return information about the device with id = deviceId. This information is primarily for the ProcDMXGetInputAttributes() function, which does not have access to the appropriate data structure.

int dmxGetInputCount (  void   )

Return the total number of devices, not just dmxNumInputs. The number returned should be the same as that returned by XListInputDevices.

unsigned long dmxGetNumScreens (  void   )

Return the value of dmxNumScreens -- the total number of backend screens in use (these are logical screens and may be larger than the number of backend displays).

Bool dmxGetScreenAttributes (  int  physical, DMXScreenAttributesPtr  attr )

This routine provides information to the DMX protocol extension about a particular screen.

Bool dmxGetWindowAttributes (  WindowPtr  pWindow, DMXWindowAttributesPtr  attr )

This routine provides information to the DMX protocol extension about a particular window.

int dmxRemoveInput (  int  id  )

Remove the input with physical id id.
