Required ColorSync Manager Request Codes
Your CMM must also be able to handle the required ColorSync Manager request codes defined by these constants:

kCMMInit (0)
Requests that you initialize the current component instance of your CMM for a ColorSync 1.0 session. This is a required request code only if your CMM supports ColorSync 1.0 profiles.
kCMMMatchColors (1)
Requests that you color match the specified colors from one color space to another. For more information, see "Matching a List of Colors to the Destination Profile's Color Space" (page 5-23).
kCMMCheckColors (2)
Requests that you check the specified colors against the gamut of the destination device whose profile is specified. For more information, see "Checking a List of Colors" (page 5-24).
kNCMMInit (6)
Requests that you initialize the current component instance of your CMM for a ColorSync Manager 2.x session. For more information, see "Initializing the Current Component Instance for a Session Involving Two Profiles" (page 5-22).
