/**
 * @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
 * assignment 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
 * };
