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

          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 the color argument 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.

          This function returns nonzero status if the format for the
          new white point is valid; otherwise, it returns zero.


          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.
