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.
