NAME
       XcmsCreateCCC, XcmsFreeCCC - creating and destroying CCCs

SYNTAX

       XcmsCCC  XcmsCreateCCC(Display  *display, int screen_number, Visual *vi-
              sual, XcmsColor *client_white_point, XcmsCompressionProc compres-
              sion_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 proce-
                 dure or NULL.

       compression_proc
                 Specifies the gamut compression procedure that is  to  be  ap-
                 plied  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  encoun-
                 ters  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  de-
                 sired.

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.
