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 specifica-
       tion 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 speci-
       fied CCC with the newly specified procedure and client
       data and then returns the old procedure.
