ARGUMENTS

display Specifies the connection to the X server.

ccc Specifies the CCC.

client_white_point
Specifies the Client White Point. If NULL is specified,
the Client White Point is to be assumed to be the same as
the Screen White Point. Note that the pixel member is
ignored.

compression_client_data
Specifies client data for use by the gamut compression
procedure or NULL.

compression_proc
Specifies the gamut compression procedure that is to be
applied when a color lies outside the screen's color gamut.
If NULL is specified and a function using this CCC must
convert a color specification to a device-dependent format
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
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.

Note that default CCCs and those currently associated with colormaps
are ignored.
