NAME
       XcmsSetWhitePoint, XcmsSetWhiteAdjustProc - modifying CCC attributes

SYNTAX
       Status XcmsSetWhitePoint(ccc, color)
             XcmsCCC ccc;
             XcmsColor *color;

       XcmsWhiteAdjustProc XcmsSetWhiteAdjustProc(ccc, whiteadjustproc,
       clientdata)
             XcmsCCC ccc;
             XcmsWhiteAdjustProc whiteadjustproc;
             XPointer clientdata;

ARGUMENTS
       ccc       Specifies the CCC.

       clientdata
                 Specifies client data for the white point adjustment
                 procedure or NULL.

       color     Specifies the new Client White Point.

       whiteadjustproc
                 Specifies the white point adjustment procedure.

DESCRIPTION
       The XcmsSetWhitePoint function changes the Client White Point in the
       specified CCC.  Note that the pixel member is ignored and that the
       color specification is left unchanged upon return.  The format for
       the new white point must be XcmsCIEXYZFormat, XcmsCIEuvYFormat,
       XcmsCIExyYFormat, or XcmsUndefinedFormat.  If color is NULL, this
       function sets the format component of the Client White Point
       specification to XcmsUndefinedFormat, indicating that the Client
       White Point is assumed to be the same as the Screen White Point.

       The XcmsSetWhiteAdjustProc function first sets the white point
       adjustment procedure and client data in the specified CCC with the
       newly specified procedure and client data and then returns the old
       procedure.
