XcmsSetWhitePoint(3)            XLIB FUNCTIONS            XcmsSetWhitePoint(3)

NAME
       XcmsSetWhitePoint, XcmsSetWhiteAdjustProc - modifying CCC attributes

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

       XcmsWhiteAdjustProc  XcmsSetWhiteAdjustProc(XcmsCCC  ccc,  XcmsWhiteAd-
              justProc white_adjust_proc, XPointer client_data);

ARGUMENTS
       ccc       Specifies the CCC.

       client_data
                 Specifies client data for the white point  adjustment  proce-
                 dure 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, XcmsCIExyY-
       Format,  or  XcmsUndefinedFormat.   If the color argument 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.

       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 adjust-
       ment procedure and client data in the  specified  CCC  with  the  newly
       specified procedure and client data and then returns the old procedure.
