ARGUMENTS

17       display   Specifies the connection to the X server.
18
19       ccc       Specifies the CCC.
20
21       client_white_point
22                 Specifies the Client White Point.  If NULL is specified,  the
23                 Client  White  Point  is  to be assumed to be the same as the
24                 Screen White Point.  Note that the pixel member is ignored.
25
26       compression_client_data
27                 Specifies client data for use by the gamut compression proce‐
28                 dure or NULL.
29
30       compression_proc
31                 Specifies  the  gamut compression procedure that is to be ap‐
32                 plied when a color lies outside the screen's color gamut.  If
33                 NULL  is specified and a function using this CCC must convert
34                 a color specification to a device-dependent  format  and  en‐
35                 counters  a color that lies outside the screen's color gamut,
36                 that function will return XcmsFailure.
37
38       screen_number
39                 Specifies the appropriate screen number on the host server.
40
41       visual    Specifies the visual type.
42
43       white_adjust_client_data
44                 Specifies client data for use with the white point adjustment
45                 procedure or NULL.
46
47       white_adjust_proc
48                 Specifies  the  white  adjustment procedure that is to be ap‐
49                 plied when the Client White Point  differs  from  the  Screen
50                 White  Point.   NULL indicates that no white point adjustment
51                 is desired.

DESCRIPTION

54       The XcmsCreateCCC function creates a CCC  for  the  specified  display,
55       screen, and visual.
56
57       The  XcmsFreeCCC  function frees the memory used for the specified CCC.
58       Note that default CCCs and those currently  associated  with  colormaps
59       are ignored.
