std::experi...ource::reset(3) C++ Standard Libarystd::experi...ource::reset(3) NAME std::experimental::unique_resource::reset - std::experimen- tal::unique_resource::reset Synopsis void reset() noexcept; (1) (library fundamentals TS v3) template <class RR> (2) (library fundamentals TS v3) void reset( RR&& r ); 1) Disposes the resource by calling the deleter with the underlying resource handle if the unique_resource owns it. The unique_resource does not own the resource after the call. 2) Replaces the resource by calling (1) and then assigns the stored resource handle with std::forward<RR>(r) if std::is_nothrow_assignable_v<RS, RR> is true, otherwise std::as_const(r), where RS is the type of stored resource handle. The unique_resource owns the resource after the call. If copy-assignment of the store resource handle throws an exception, calls del_(r), where del is the deleter object. This overload participates in overload resolution only if the se- lected assignment expression assigning the stored resource handle is well-formed. The program is ill-formed if del_(r) is ill-formed. The behavior is undefined if del_(r) results in undefined behavior or throws an exception. Parameters r - resource handle for a new resource to manage Return value (none) Exceptions 2) Any exception thrown in assigning the stored resource handle. Notes The mechanism ensures no leaking of resources.
