- ccc
- Specifies the CCC.

- 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.
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.
