std::experimental::unique_resource<R, D>::reset
From cppreference.com
< cpp | experimental | unique resource
| void reset() noexcept; |
(1) | (library fundamentals TS v3) |
| template <class RR> void reset( RR&& r ); |
(2) | (library fundamentals TS v3) |
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. This overload only participates in overload resolution if the selected assignment expression assigning the stored resource handle is well-formed.
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.
