20.11 Smart pointers [smartptr]

20.11.1 Unique-ownership pointers [unique.ptr]

20.11.1.2 Default deleters [unique.ptr.dltr]

20.11.1.2.3 default_­delete<T[]> [unique.ptr.dltr.dflt1]

namespace std { template<class T> struct default_delete<T[]> { constexpr default_delete() noexcept = default; template<class U> default_delete(const default_delete<U[]>&) noexcept; template<class U> void operator()(U* ptr) const; }; }
template<class U> default_delete(const default_delete<U[]>& other) noexcept;
Constraints: U(*)[] is convertible to T(*)[].
Effects: Constructs a default_­delete object from another default_­delete<U[]> object.
template<class U> void operator()(U* ptr) const;
Constraints: U(*)[] is convertible to T(*)[].
Mandates: U is a complete type.
Effects: Calls delete[] on ptr.
