:relfileprefix: ../
:mrdocs:

This `struct` template implements the `add_volatile` meta‐function defined in the C++11 standard [meta.trans.cv], providing an alias, `type`, that returns the result. If the (template parameter) `t_TYPE` is not a reference type, nor a function type, nor already `volatile`‐qualified at the top‐level, then `type` is an alias to `t_TYPE` with a top‐level `volatile`‐qualifier added; otherwise, `type` is an alias to `t_TYPE`.
