Re: [Boost-users] query regarding mutex

This is how mutex class looks like

#include class mutex:    boost::noncopyable { public:    mutex();    ~mutex();    void lock();    bool try_lock();    void unlock();    typedef platform-specific-type native_handle_type;    native_handle_type native_handle();    typedef unique_lock<mutex> scoped_lock;

   typedef unspecified-type scoped_try_lock;

};

Please help me figure out what purpose does 'unspecified-type' serve below.

Note that this is just documentation, not the real class definition.
