Purpose
Use
GPQACF to inquire the actual color
capabilities of the specified workstation.

the maximum number of colors available,
and data indicating if color is supported
on the specified workstation.
If the inquired information is available,
then the graPHIGS API sets the error indicator to zero
and returns the values in the output parameters.
If the inquired information is unavailable, then
the error indicator
(errind)
contains an error number indicating the reason,
and the values returned in the output parameters
are unpredictable.
