void release() noexcept;		(library fundamentals TS v3)

Releases the ownership of the managed resource if any. The destructor will not execute the deleter after the call, unless reset is called later for managing new resource.

Unlike std::unique_ptr::release, this function is not required to modify the stored resource handle.

Parameters

(none)

Return value

(none)

Example

release

returns a pointer to the managed object and releases the ownership (public member function of std::unique_ptr<T,Deleter>)
