23.11 Smart pointers [smartptr]

23.11.1 Class template unique_­ptr [unique.ptr] unique_­ptr for array objects with a runtime length [unique.ptr.runtime] unique_­ptr modifiers [unique.ptr.runtime.modifiers]

void reset(nullptr_t p = nullptr) noexcept;

Effects: Equivalent to reset(pointer()).

template <class U> void reset(U p) noexcept;

This function behaves the same as the reset member of the primary template, except that it shall not participate in overload resolution unless either

  • 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(*)[].
