boost asio

Source: http://blog.csdn.net/pud_zha/article/details/37561011 Work is a small helper class that supports only constructors and destructors. (There is also a get_io_service returned by the associated Io_service) when constructing a work,

Let's take a look at the elegant exit, but there are still some imperfections. When receiving the exit signal, io_service is directly disabled, instead of closing all connections and then exiting. In fact, three things should be done in order: 1.

As mentioned in the libev demo, how does epoll work? to better reach the underlying layer, we use epoll APIs to design an echoserver. The client code is the same as the previous one. Echoserver. cpp is as follows: #include #include

Start with newlispProgramTest, initiate a connection, send a correct character 'a', connect continuously, then send an error character, disconnect. The test script is as follows: (Define (quit-for-error) (println (net-error) (exit) (set 'socket (

The previous article is very simple and easy to understand. However, in C ++, you still need to encapsulate the code that can be used in multiple projects. The following cancels the global variable, creates a server class, provides the run function,

Newlisp provides a simple method for me to create multiple processes. The following program creates 10 processes, each of which sends several 'A' and finally sends a 'q '. (define (quit-for-error) ((println (net-error)) (exit)))(define (send-test)

First, let's take a look at the first line of code. The first line of code defines a core

(Original) Open the fog to see the moon-analyze the proactor mode in asio (2), asioproactor In the previous blog, we mentioned that asynchronous requests are forwarded from the upper layer to the win_iocp_socket_service object at the bottom of the service layer, which forwards requests to the Operating System (Calling windows APIs ), how does the operating system return the result to the application after processing the asynchronous request? Here, it

Ace is a very mature middleware product. It is an adaptive communication environment, but it is too ambitious. There are a bunch of design patterns, and the architecture is layer after layer. It is a little difficult for beginners. ASIO is a basic asynchronous Io library developed by boost. It encapsulates socket and simplifies socket-based Program Development. Recently analyzed

Http://www.cnblogs.com/zhiranok/archive/2011/12/12/boost_asio.html on front side As I mentioned, to address the problems encountered in boost ASIO, encapsulate ASIO with the following goals: 1. Create a socket and acceptor and no longer construct io_service by yourself. Because the objects in ASIO need to save the
