# AEStreamSetRecordType(_:_:)

Sets the type of the most recently created record in an AEStreamRef.

## Declaration

```swift
func AEStreamSetRecordType(_ ref: AEStreamRef!, _ newType: DescType) -> OSStatus
```

## Parameters

- `ref`: An doc://com.apple.documentation/documentation/coreservices/aestreamref containing the stream data.
- `newType`: The new type code for the AERecord being added to the stream. See doc://com.apple.documentation/documentation/coreservices/desctype.

## Return Value

Return Value A result code. See Result Codes.

## Discussion

Discussion Use this routine to change the type of a record after it has been opened. You must call this routine between calls to AEStreamOpenRecord(_:_:) and AEStreamCloseRecord(_:). The type you specify in the newType parameter replaces the previous type specified by AEStreamOpenRecord(_:_:).
