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
Specifies the white adjustment procedure that is to be applied 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.
The XcmsFreeCCC function frees the memory used for the specified CCC. Note that default CCCs and those currently associated with colormaps
are ignored.
