DESCRIPTION

27       The  XcmsSetWhitePoint  function  changes the Client White Point in the
28       specified CCC.  Note that the pixel member  is  ignored  and  that  the
29       color  specification is left unchanged upon return.  The format for the
30       new white point must be XcmsCIEXYZFormat, XcmsCIEuvYFormat, XcmsCIExyY‐
31       Format,  or  XcmsUndefinedFormat.   If the color argument is NULL, this
32       function sets the format component of the Client White Point specifica‐
33       tion  to XcmsUndefinedFormat, indicating that the Client White Point is
34       assumed to be the same as the Screen White Point.
35
36       This function returns nonzero status if the format for  the  new  white
37       point is valid; otherwise, it returns zero.
38
39
40       The  XcmsSetWhiteAdjustProc function first sets the white point adjust‐
41       ment procedure and client data in the  specified  CCC  with  the  newly
42       specified procedure and client data and then returns the old procedure.
