# vDSP_DFT_DestroySetupD

Releases a double-precision setup structure.

## Declaration

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

## Parameters

- `__Setup`: The setup structure to destroy.

## Discussion

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.
