# compression_stream_destroy(_:)

Frees any memory allocated by stream initialization function.

## Declaration

```swift
func compression_stream_destroy(_ stream: UnsafeMutablePointer<compression_stream>) -> compression_status
```

## Parameters

- `stream`: A pointer to an allocated and initialized doc://com.apple.compression/documentation/Compression/compression_stream structure.

## Return Value

Return Value A value of type compression_status, interpreted as follows: COMPRESSION_STATUS_OK means that the function successfully destroyed the stream. COMPRESSION_STATUS_ERROR means an error occurred. Discussion Note that compression_stream_destroy(_:) doesn’t free the stream object or the buffers allocated by the caller.
