NAME

std::experimental::unique_resource::reset - std::experimental::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 selected 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.
