这是因为Boost.Asio在添加了其他I / O对象之前很早就支持网络功能。 网络功能非常适合异步操作，因为通过...
使用下面的代码: sock.async_receive(some_buffer, on_read); 实例some_buffer需要满足一些需求,叫做ConstBufferSequence或者MutableBufferSequence(你可以在Boost.Asio的文档中查看它们)。创建你自己的类去处理这些需求的细节是非常复杂的,但是Boost.Asio已经提供了一些类用来处理这些需求。所以你不用直接访问这些缓冲区,...

当然你可以使用 boost::asio::io_service::strand让完成事件处理器的调用,在同一时间只有一个, 比如下面的的代码: socket_.async_read_some(boost::asio::buffer(buffer_), strand_.wrap( boost::bind(&connection::handle_read, shared_from_this(), ...
4)异步连接:由于async_connect只接受boost::basic_socket类即最底层的socket作为参数,因此需要调用lowest_layer。1void handle_resolve(const boost::system::error_code& e,boost::asio::ip::tcp::resolver::iterator endpoint_iterator)2{3 if (!e)4 boost::asio::async_connect(socket_->lowest_layer(), ...
