20.3 Smart pointers [smartptr]

20.3.1 Unique-ownership pointers [unique.ptr] unique_ptr for array objects with a runtime length [unique.ptr.runtime] Modifiers [unique.ptr.runtime.modifiers]

constexpr void reset(nullptr_t p = nullptr) noexcept;
Effects: Equivalent to reset(pointer()).
template<class U> constexpr void reset(U p) noexcept;
This function behaves the same as the reset member of the primary template.
  • U is the same type as pointer, or
  • pointer is the same type as element_type*, U is a pointer type V*, and V(*)[] is convertible to element_type(*)[].
