Got "Bad file descriptor" when use boost::asio and boost::thread

Your socket is a temporary object, you pass a reffence to it but the object is going out of the scope and being destroyed before the thread process it. Use shared_ptr<socket>
or keep them in a container.

int func(boost::asio::ip::tcp::socket &socket) { boost::system::error_code ec; socket.write_some(boost::asio::buffer("hello world!"), ec); cout << socket.is_open() << endl; if(ec) { cout << boost::system::system_error(ec).what() << endl; } return 0; } int main(int argc, char* argv[]) { using namespace boost::asio; io_service iosev; ip::tcp::acceptor acceptor(iosev, ip::tcp::endpoint(ip::tcp::v4(), 1000)); while(1) { ip::tcp::socket socket(iosev); acceptor.accept(socket); boost::thread t = boost::thread(func, boost::ref(socket)); } return 0; }
I want one new thread handle new connection. But in function "func", the socket is not open and I got "Bad file descriptor". I read some examples in the document and web, but they are async. I think it's not necessary for my simple demand.
How can I fix the error? Any help is appreciated
