asio interface

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

In fact, these functions call the do_one function, which is used to obtain the complete port status. All timers and network events are scheduled through do_one, do_one function prototype: size_t do_one(bool block, boost::system::error_code& ec) Its

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 (

Document directory Commands in FTP Someone else's code was slightly modified. Boost1.50 and vs2008 can be compiled successfully. ----------- Test_ftp.cpp --------------- // Ftp_asio.cpp: defines the entry point of the console application. ////

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,

This section first refactor the code. The business logic code and the communication infrastructure code need to be decoupled. The business logic code processes the protocols in the communication process and the application logic behind them.

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)
