Yes, timeout and read event have two different callback, in read callback you have to m_timer->cancel() to avoid receive timeout also. ----- Messaggio originale ----- Da: Arkadiy Vertleyb A: boost-users@lists.boost.org Inviato: Martedì 4 dicembre 2007, 16:14:40 Oggetto: Re: [Boost-users] [asio] how to specify a timeout? Hello Andrea, "Andrea Bartoli" wrote

Use an asio::deadline_timer

Example:

asio::io_service m_ioService; asio::deadline_timer * m_timer; m_timer = new asio::deadline_timer(m_ioService);

m_timer->expires_from_now( boost::posix_time::seconds(t) ); m_timer->async_wait( boost::bind(&Foo:handle_timeout, this, asio::placeholders::error) ); asio::async_read( *m_socket, asio::buffer( m_msg.header(), m_msg.header_length() ),

boost::bind(&Foo::handle_read_header,

this, asio::placeholders::error) );

Thanks for your response. Still, it's not clear to me how to use it. In your example it seems that read operation and timeout are two independent things. How do I make sure only one of these two fires? Is it possile to cancel read operation once timout has been recieved?
