class locked_release

Detailed Description

An object pointer that uses mutex to assure thread-safe singleton use.

This class is used to support a threadsafe replacable pointer to a object. This class is used to form and support the templated locked_pointer class and used with the locked_release class. An example of where this might be used is in config file parsers, where a seperate thread may process and generate a new config object for new threads to refernce, while the old configuration continues to be used by a reference counted instance that goes away when it falls out of scope.
