XcmsFreeCCC(3)


NAME

   XcmsCreateCCC, XcmsFreeCCC - creating and destroying CCCs

SYNTAX

   XcmsCCC XcmsCreateCCC(Display *display, int screen_number, Visual
          *visual, XcmsColor *client_white_point, XcmsCompressionProc
          compression_proc, XPointer compression_client_data,
          XcmsWhiteAdjustProc white_adjust_proc, XPointer
          white_adjust_client_data);

   void XcmsFreeCCC(XcmsCCC ccc);

ARGUMENTS

   display   Specifies the connection to the X server.

   ccc       Specifies the CCC.

   client_white_point
             Specifies the Client White Point.  If NULL is specified, the
             Client White Point is to be assumed to be the same as the
             Screen White Point.  Note that the pixel member is ignored.

   compression_client_data
             Specifies client data for use by the gamut compression
             procedure or NULL.

   compression_proc
             Specifies the gamut compression procedure that is to be
             applied when a color lies outside the screen's color gamut.
             If NULL is specified and a function using this CCC must
             convert a color specification to a device-dependent format
             and encounters a color that lies outside the screen's color
             gamut, that function will return XcmsFailure.

   screen_number
             Specifies the appropriate screen number on the host server.

   visual    Specifies the visual type.

   white_adjust_client_data
             Specifies client data for use with the white point adjustment
             procedure or NULL.

   white_adjust_proc
             Specifies the white adjustment procedure that is to be
             applied when the Client White Point differs from the Screen
             White Point.  NULL indicates that no white point adjustment
             is desired.

DESCRIPTION

   The XcmsCreateCCC function creates a CCC for the specified display,
   screen, and visual.

   The XcmsFreeCCC function frees the memory used for the specified CCC.
   Note that default CCCs and those currently associated with colormaps
   are ignored.
