/**
* @class ACE_Copy_Disabled
*
* @brief Helper class to disable copy construction and assignment
*
* Classes used to control OS and other resources are not "canonical",
* i.e. they have their copy constructor and assignment operators
* disabled.
* This is often done by making the copy constructor and assignment
* operators private, effectively disallowing copying by clients of
* the class (including derived classes). If the copy constructor and
* assingment operators are left unimplemented then the class itself
* cannot make any copies of its instances, because it would result in
* link errors.
*
* To use this class simply use private inheritance:
*
* class Foo : private ACE_Copy_Disabled
* {
* // code here
* };
