       XcmsCCC XcmsCreateCCC(display, screennumber, visual,
       clientwhitepoint, compressionproc,
                           compressionclientdata,

             Display *display;
             int screennumber;
             Visual *visual;
             XcmsColor *clientwhitepoint;
             XcmsCompressionProc compressionproc;
             XPointer compressionclientdata;
             XcmsWhiteAdjustProc whiteadjustproc;
             XPointer whiteadjustclientdata;

       void XcmsFreeCCC(ccc)
             XcmsCCC ccc;

ARGUMENTS
       display   Specifies the connection to the X server.

       ccc       Specifies the CCC.

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

       compressionclientdata
                 Specifies client data for use by the gamut com-
                 pression procedure or NULL.

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

       screennumber
                 Specifies the appropriate screen number on the
                 host server.

       visual    Specifies the visual type.

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

       whiteadjustproc
                 Specifies the white adjustment procedure that is
                 to be applied when the Client White Point dif-
                 fers from the Screen White Point.  NULL indi-
                 cates 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.
