[Boost-users] [ASIO] async_accept : Error m_val 1.

9 Mar 2011

      Hello,

I'm currently developping a tcp server with boost asio with vs2010 on win 7.
My server class:

Header file:

class Server
{
 private:
        boost::asio::io_service &_io;
        boost::asio::ip::tcp::acceptor *acceptor;
        bool                connected;
        boost::asio::ip::tcp::socket *_client;
};

Source file:

Server::Server(boost::asio::io_service& io) : _io(io)
{
  connected = false;
}

void                Server::receiving()
{
        boost::system::error_code error;
        acceptor = new tcp::acceptor(_io, tcp::endpoint(tcp::v4(), 14242));
        _client = new tcp::socket(_io);
        connected = false;
        try {
                acceptor->async_accept(*_client, boost::bind(&Server::handle_accept, this, boost::asio::placeholders::error));
        } catch(...) {
        }
}

void                Server::handle_accept(const boost::system::error_code& error)
{
// problem appears here
}

In main function, i'm running io.run();
I'm using in another class boost asio as a tcp client (which work properly) with the same io_service.
When a tcp client connect to boost asio tcp server (Class Server), handle_accept is called. error has the following values:

m_val = 1;
m_cat = 0x00ab8d00 instance;
 | [boost::asio::error::detail::misc_category] = {...}
 | boost::noncopyable_::noncopyable = {...}
 | __vfptr = 0x00a8bf18 const boost::asio::error::detail::misc_category::`vftable'
   | [0] = 0x0098aaaa boost::asio::error::detail::misc_category::`scalar deleting destructor'(unsigned int)
   | [1] = 0x0098b4e1 boost::asio::error::detail::misc_category::name(void)
   | [2] = 0x0098b603 boost::asio::error::detail::misc_category::message(int)
   | [3] = 0x0098e39e boost::system::error_category::default_error_condition(int)
   | [4] = 0x0098bef0 boost::system::error_category::equivalent(class boost::system::error_code const &,int)
   | [5] = 0x0098cb61 boost::system::error_category::equivalent(int,class boost::system::error_condition const &)

Do anyone know what does it mean?
Can you help me to fix it?
Thank you !
