The Mutex need not supply all of this functionality. If the client of scoped_lock&lt;Mutex&gt; does not use functionality which the Mutex does not supply, no harm is done. Mutex ownership transfer is supported through the syntax of move semantics. Ownership transfer is allowed both by construction and assignment. The <link linkend="doxygen.boost_interprocess_header_reference.classboost_1_1interprocess_1_1scoped__lock">scoped_lock</link> does not support copy semantics.
