# vDSP_DFT_DestroySetupD

Releases a double-precision setup structure.

```
void vDSP_DFT_DestroySetupD(vDSP_DFT_SetupD __Setup);
```

## Parameters

`__Setup`

The setup structure to destroy.

## Discussion

Destroying a setup with shared data is safe; this function only releases memory that’s not needed by other undestroyed setups.

> Note:
> This function isn’t fully thread-safe. You must not call this function concurrently with any function that uses the setup structure or any other setup structure that shares its underlying storage.
