Type Property

opaqueMemory

Take no action when pointers are deleted.

Declaration

static var opaqueMemory: NSPointerFunctions.Options { get }

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.
