At a minimum, your CMM must handle the required Component Manager and required ColorSync Manager request codes. The required Component Manager request codes are defined by these constants:
kComponentVersionSelect
(
-4
) Requests that you return your CMM's version number. For more information, see
Providing Your CMM Version Number
. Note that if you provide your version number in an extended component resource, the Component Manager can obtain the version number without having to call your code that handles this request code.
