# CMRemoveAllAttachments(_:)

Removes all attachments from an attachment bearer object.

## Declaration

```swift
func CMRemoveAllAttachments(_ target: CMAttachmentBearer)
```

## Parameters

- `target`: The CMAttachmentBearer whose attachment you want to remove.

## Discussion

Discussion While CMRemoveAttachment removes a specific attachment identified by a key, CMRemoveAllAttachments removes all attachments of a CMAttachmentBearer and decrements their retain counts.  Given a CVBuffer, CMRemoveAllAttachments is equivalent to CVBufferRemoveAllAttachments.
