Function Documentation

void dmxBackendCollectEvents (  DevicePtr  pDev, dmxMotionProcPtr  motion, dmxEnqueueProcPtr  enqueue, dmxCheckSpecialProcPtr  checkspecial, DMXBlockType  block )

Get events from the X queue on the backend servers and put the events into the DMX event queue.

pointer dmxBackendCreatePrivate (  DeviceIntPtr  pDevice  )

Create and return a private data structure.

void dmxBackendDestroyPrivate (  pointer  private  )

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

int dmxBackendFunctions (  pointer  private, DMXFunctionType  function )

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

void dmxBackendInit (  DevicePtr  pDev  )

Initialized the backend device described by pDev.

void dmxBackendKbdGetInfo (  DevicePtr  pDev, DMXLocalInitInfoPtr  info )

Get information about the backend keyboard (for initialization).

void dmxBackendLateReInit (  DevicePtr  pDev  )

Re-initialized the backend device described by pDev (after a reconfig).

void dmxBackendMouGetInfo (  DevicePtr  pDev, DMXLocalInitInfoPtr  info )

Get information about the backend pointer (for initialization).

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.

void dmxBackendUpdatePosition (  pointer  private, int  x, int  y )

This routine is called from #dmxCoreMotion for each motion event. #x and #y are global coordinants.
