# opaqueMemory

Take no action when pointers are deleted.

## Declaration

```swift
static var opaqueMemory: NSPointerFunctions.Options { get }
```

## Discussion

Discussion This is usually the preferred memory option for holding arbitrary pointers. This is essentially a no-op relinquish function; the acquire function is only used for copy-in operations.  This option is unlikely a to be a good choice for objects.
