void dmxBackendCollectEvents ( DevicePtr  pDev,

dmxEnqueueProcPtr  enqueue,
dmxCheckSpecialProcPtr  checkspecial,
DMXBlockType  block 
)
static void dmxBackendComputeCenter ( myPrivate priv  )  [static]
pointer dmxBackendCreatePrivate ( DeviceIntPtr  pDevice  ) 

Create and return a private data structure.

References GETDMXLOCALFROMPDEVICE.

void dmxBackendDestroyPrivate ( pointer  private  ) 

Destroy the private data structure. No checking is performed to verify that the structure was actually created by dmxBackendCreatePrivate.

static int dmxBackendFindOverlapping ( myPrivate priv,
int  screen,
int  x,
int  y 
) [static]
static DMXScreenInfo* dmxBackendFindWindow ( myPrivate priv,
Window  win 
) [static]
int dmxBackendFunctions ( pointer  private,
DMXFunctionType  function 
)

Process DMXFunctionType functions. The only function handled here is to acknowledge a pending server shutdown.

XEvent *  X

static DMXScreenInfo* dmxBackendPendingMotionEvent ( myPrivate priv,

void dmxBackendProcessInput ( pointer  private  ) 

Called after input events are processed from the DMX queue. No event processing actually takes place here, but this is a convenient place to update the pointer.
