Detailed Description

template<class TYPE, class ACE_LOCK>
class ACE_Unmanaged_Singleton< TYPE, ACE_LOCK >

Same as ACE_Singleton, except does _not_ register with ACE_Object_Manager for destruction.

This version of ACE_Singleton can be used if, for example, its DLL will be unloaded before the ACE_Object_Manager destroys the instance. Unlike with ACE_Singleton, the application is responsible for explicitly destroying the instance after it is no longer needed (if it wants to avoid memory leaks, at least). The close() static member function must be used to explicitly destroy the Singleton. Usage is the same as for ACE_Singleton, but note that if you you declare a friend, the friend class must still be an *ACE_Singleton*<T, [ACE_LOCK]>, not an ACE_Unmanaged_Singleton.
