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.
