     NAME
          XcmsCreateCCC, XcmsFreeCCC - creating and destroying CCCs

     SYNTAX
          XcmsCCC XcmsCreateCCC(display, screen_number, visual,
          client_white_point, compression_proc,
                              compression_client_data,
          white_adjust_proc, white_adjust_client_data)
                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(ccc)
                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.
