cc_cd    -  This is  security pointer, so that when this  structure pointer
            is  being passed somewhere  alone then  there is still a way to
            access root parameters.

cc_imsg  -  This  is packed  pointer so that no pseudo-interrupt  will  eat 
            stack  where  Intuition messages  are being  dispatched. Just a
            helper one that does not matter in normal operation.

cc_mainwin
         -  Window that is now associated with the console handler. Just do
            not close it from code and everything will be OK.

cc_con   -  Console  FileHandle  that is BPTR  which is an interface to the
            handler which talks to cc_mainwin. Calling 'Close()' will close
            the window!

cc_idcmp -  IDCMP  index that represents particular  IDCMP  message. Attach
            your pseudo-interrupt function here by converting message ID to
            index. Use the respective function to add/del!

cc_index -  This is  being used in the IDCMP pseudo-interrupt dispatcher to
            reduce stack usage.

cc_numwin
         -  Number of  this very window. All windows are enumerated so that
            it is easy to identify them. First window has a value of 0.

cc_zoomed
         -  Kludgy zoom/size indicator used to mark changes globally.

cc_zoomfct
         -  Current zoom factor this window will scale with. Zoom factor is
            normally expressed in % and can range form 1 to 100.

cc_rpylim
         -  Maximum pixels in Y axis logo can take from top to bottom. This
            is freely setable. The default value is QDEV_CTL_PRV_REPOSLIM.

cc_iflags
         -  Image  related flags that apply  to this very window. These are
            defined as QDEV_MEM_IFLPIC_#? group.

cc_lflags
         -  Logo  playback flags that apply to this  very window. These are
            defined as QDEV_CTL_LFLLOGO_#? group.
