Meta‐function that converts an array type to a `const` pointer type.

== Synopsis

Declared in `<bslmf_arraytopointer.h>`

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

== Description

This meta‐function provides a nested `Type` alias that is a pointer to `const` element type when the (template parameter) `t_TYPE` is an array, and is `const t_TYPE` itself otherwise. Use this when an explicitly `const` pointer type is required.
