Smart pointer for handling referenced counted objects.
◆ release()
release the pointer from ownership by this ref_ptr<>, decrementing the objects refencedCount() via unref_nodelete() to prevent the Object object from being deleted even if the reference count goes to zero.
Use when using a local ref_ptr<> to an Object that you want to return from a function/method via a C pointer, whilst preventing the normal ref_ptr<> destructor from cleaning up the object. When using release() you are implicitly expecting other code to take over management of the object, otherwise a memory leak will result.
