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.

no white point adjustment is desired.
