  23 /*  FUNCTION
  24         Gets a certain attribute from a given video layer. You have to call
  25         LockVLayer() to make sure that the result is valid !
  26
  27     INPUTS
  28         VLayerHandle - pointer to a previously created videolayer handle
  29
  30         AttrNum - attribute that you want to get
  31
  32     RESULT
  33         value - the value for the given attribute

  35     NOTES
  36         Attributes available are:
  37
  38         VOA_BaseAddress -       if this attribute is specified the base address for
  39                                 the source data is returned
  40
  41         VOA_ColorKeyPen -       returns the pen number used for color keying. If color
  42                                 keying is not enabled, -1 is returned
