# CMEndMatching

Concludes a QuickDraw-specific ColorSync matching session initiated by a previous call to the `NCMBeginMatching` function. 

## Declaration

```occ
void CMEndMatching (
   CMMatchRef myRef
);
```

## Parameters

- `myRef`: A reference to the matching session to end. This reference was previously created and returned by a call to `NCMBeginMatching` function. See the QuickDraw Reference for a description of the PixMap data type.

## Overview

The `CMEndMatching` function releases private memory allocated for the QuickDraw-specific matching session. 

After you call the `NCMBeginMatching` function and before you call `CMEndMatching` to end the matching session, embedded color-matching picture comments, such as `cmEnableMatching` and `cmDisableMatching`, are not acknowledged.
