NAME
      XcmsSetWhitePoint, XcmsSetWhiteAdjustProc - modifying CCC attributes

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

      XcmsWhiteAdjustProc XcmsSetWhiteAdjustProc(ccc, white_adjust_proc,
      client_data)
            XcmsCCC ccc;
            XcmsWhiteAdjustProc white_adjust_proc;
            XPointer client_data;

ARGUMENTS
      ccc       Specifies the CCC.

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

      color     Specifies the new Client White Point.

      white_adjust_proc
                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.
