A specialization for array types is provided with a slightly altered interface.
Conversions between different types of unique_ptr<T[], D> or to or from the non-array forms of unique_ptr produce an ill-formed program.
Pointers to types derived from T are rejected by the constructors, and by reset.
The observers operator* and operator-> are not provided.
The indexing observer operator[] is provided.
The default deleter will call delete[].
Descriptions are provided below only for member functions that have behavior different from the primary template.
The template argument T shall be a complete type.
20.8.1.3.1 unique_ptr constructors [unique.ptr.runtime.ctor] explicit unique_ptr(pointer p) noexcept; unique_ptr(pointer p, see below d) noexcept; unique_ptr(pointer p, see below d) noexcept;
These constructors behave the same as in the primary template except that they do not accept pointer types which are convertible to pointer. [ Note: One implementation technique is to create private templated overloads of these members. — end note ]
