# CMProfileModified

Indicates whether the specified profile has been modified since it was created or last updated.

## Declaration

```occ
CMError CMProfileModified (
   CMProfileRef prof,
   Boolean *modified
);
```

## Parameters

- `prof`: A profile reference of type [doc://com.apple.documentation/documentation/applicationservices/cmprofileref](applicationservices/cmprofileref.md) to the profile to examine.
- `modified`: A pointer to a Boolean variable. On return, the value of `modified` is set to `true` if the profile has been modified, `false` if it has not.

## Return Value

A `CMError` value. See [Result Codes](../colorsync_manager.md).

## Overview

When a profile is first opened, its modified flag is set to `false`. On calls that add to, delete from, or set the profile header or tags, the modified flag is set to `true`. After calling the function [CMUpdateProfile](1804864-cmupdateprofile.md), the modified flag is reset to `false`.
