Detailed Description

template<class ReferenceCounted, class = typename std::enable_if<std::is_base_of<IReferenceCounted, ReferenceCounted>::value>::type>
class irr_ptr< ReferenceCounted, class >

Shared pointer for IrrLicht objects.

It should only be used for user-managed objects, i.e. those created with the new operator or create* functions, like: irr_ptr<scene::IMeshBuffer> buf{new scene::SMeshBuffer()}; The reference counting is not balanced as new objects have reference count set to one, and the irr_ptr constructor (and reset) assumes ownership of that reference.

It shouldn’t be used for engine-managed objects, including those created with addTexture and similar methods. Constructing irr_ptr directly from such object is a bug and may lead to a crash. Indirect construction is possible though; see the grab free function for details and use cases.
