Arguments
display-

when a color lies outside the screen's color gamut.
If NULL is specified and a function using this CCC

and encounters a color that lies outside the screen's color gamut,
that function will return XcmsFailure.
screen_number-
Specifies the appropriate screen number on the host server.
visual-
Specifies the visual type.
white_adjust_client_data-
Specifies client data for use with the white
point adjustment procedure or NULL.
white_adjust_proc-

when the Client White Point differs from the Screen White Point.
NULL indicates that no white point adjustment is desired.
Description
The XcmsCreateCCC function creates a
CCC for the specified display, screen, and visual.

used for the specified CCC.

associated with colormaps are ignored.
