Re: [Boost-users] timed_mutex::scoped_timed_lock

30 Aug 2006

      10x, sorry for my english
...
I am not sure what this delay function does.
this function from ${BOOSTDIR}/libs/thread/test/util.inl
...
scoped_time_lock takes boost::xtime or bool. 4 here is interpreted as
"true", not as time.
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 lock;
void
 auth ()
{
	cout << "auth" << endl;
	boost::thread::sleep ( delay(AUTHTIME));
	cout << "auth end" << endl;
	lock->unlock();
}

int
 main ()
{
	lock = (std::auto_ptr)
		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@andr> ./coolprg
auth
okey!
okey!
okey!
auth end
unlock!
