NAME
       XcmsCreateCCC, XcmsFreeCCC - creating and destroying CCCs

SYNTAX
       XcmsCCC XcmsCreateCCC(display, screennumber, visual,
       clientwhitepoint, compressionproc,
                           compressionclientdata, whiteadjustproc,
       whiteadjustclientdata)
             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 compression
                 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 functions 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.

       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 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.
