Metafunction transforming a type into a pointer to that type.

== Synopsis

Declared in `<bslmf_addpointer.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
template<class t_TYPE>
struct add_pointer;
----

== Description

This `struct` template implements the `add_pointer` meta‐function defined in the C++11 standard [meta.trans.ptr], providing an alias, `type`, that returns the result. If the (template parameter) `t_TYPE` is not a reference type, then `type` is an alias to a pointer type that points to `t_TYPE`; otherwise, `type` is an alias to a pointer type that points to the type referred to by the reference `t_TYPE`, unless it is not legal to form such a pointer type, in which case `type` is an alias for `t_TYPE`.
