std::experi...ranges::prev(3) C++ Standard Libarystd::experi...ranges::prev(3) NAME std::experimental::ranges::prev - std::experimental::ranges::prev Synopsis Defined in header <experimental/ranges/iterator> namespace { (ranges TS) constexpr /* unspecified */ prev = /* unspecified */; (customization point ob- ject) } Call signature template< Iterator I > (1) constexpr I prev( I i ); template< Iterator I > (2) constexpr I prev( I i, ranges::difference_type_t<I> n ); template< Iterator I > constexpr I prev( I i, ranges::difference_type_t<I> n, I (3) bound ); Decrements the iterator i n times, or until bound is reached, whichever comes first, and returns the decremented iterator. 1) Equivalent to --i; return i;. 2) Equivalent to ranges::advance(i, -n); return i;. 3) Equivalent to ranges::advance(i, -n, bound); return i;. Return value The decremented iterator.
