10x, sorry for my english

this function from ${BOOSTDIR}/libs/thread/test/util.inl

oops.
okey, the new version of my cool program (how i can see event of timeout?) are
///------- COOLPRG
timed_mutex mut;
#define TIMEOUT      1	
#define AUTHTIME  4	

void
  timeout ()
{
        timed_mutex::scoped_timed_lock lk (mut, delay(TIMEOUT));
        if ( lk.locked ())
                cout << "how i can see event of timeout?" << endl;
        else
                cout << "okey!" << endl;
}
std::auto_ptr<timed_mutex::scoped_timed_lock> lock;
void
 auth ()
{
        cout << "auth" << endl;
        boost::thread::sleep ( delay(AUTHTIME));
        cout << "auth end" << endl;
        lock->unlock();
}

int
 main ()
{
        lock = (std::auto_ptr<timed_mutex::scoped_timed_lock>)
                new timed_mutex::scoped_timed_lock (mut,10);

        thread_group run;
        run.create_thread ( &auth);
        run.create_thread ( &timeout);
        run.create_thread ( &timeout);
        run.create_thread ( &timeout);

        run.join_all();

        if ( !lock->locked ())
                cout << "unlock!" << endl;
}
///EOF

And result (how i can see event of timeout?):

andr_at_andr> ./coolprg
auth
okey!
okey!
okey!
auth end
unlock!
