High-Level Color-Matching-Session Reference

The ColorSync Manager defines an abstract private data structure of type CMPrivateMatchRefRecord for the color-matching-session reference. When your application calls the NCMBeginMatching function (page 3-104) to begin a high-level color-matching session, the ColorSync Manager returns a reference to the color-matching session which you must later pass to the CMEndMatching function to conclude the session.
