adjustment procedure or NULL.

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.
