asio card

The following is an example code of serial_port synchronous reading/writing to a serial port device: #include If you want to control the read/write timeout, the write method must be asynchronous. In addition, the scheduled code is added: boost::asio::deadline_timer timer(io);timer.expires_from_now(boost::posix_time::millisec(60000));timer.async_wait(boost::bind(boost::asio::serial_port::cancel, sp));

local socket). The network stack uses this state to knowWhich process to give each incoming packet to and what State to put in the header of each outgoing packet. The so-called connection is only a virtual pipeline consisting of some States saved by each endpoint of the connection. Through these statuses, the network stack knows to pass the incoming data packet to that process, and to put the status to the packet header of the sent data packet. Because of the underlying-inherently connectionle

HTTP Server Based on boost: ASIO----Blog, http://blog.csdn.net/shunqiziranhao007/article/details/8737629Date, January 1, March 29, 2013----This is an example of the boost ASIO Library (I modified some code to achieve the following effect), and implemented HTTP request packets and HTTP response packets of http1.0. Very interesting. ----HTTP----For details, see "Computer Network-top-down v4cn" p61.For more in

C + + Boost::asio programming-domain name resolution In the network communication, we usually do not use the IP address directly, but use the domain name. At this time we need to use the Reslover class to get the IP through the domain name, it can realizeURL resolution that is independent of the IP version. #include "stdafx.h" #include "boost/asio.hpp" #include "boost/shared_ptr.hpp" #include "boost/thread.hpp" #include l t;boost/lexical_cast.h

I have known myself for several recent exchanges in the industry. Network servers have been developed in windows for a long time, with a load of 1 K-2 k-4 K from a single PC, and the network performance is also gradually improved. However, most of the friends around me are developed in Linux, and I am very eye-catching. The first difference is the OS environment of the server, and the logic processing of MMORPG. In fact, a single OS is different, but it cannot be measured to compare the qual

The use of mingw to learn boost is a trigger. If you want to avoid detours, you should use the compilers that come with windows. Open-source Dongdong is really hard to see and trouble on Microsoft's platform. Let's talk about the compiling environment: win7 64-bit flagship edition, mingw 4.4, and boost 1.53. All the libraries are generated as static libraries (. a) The source file is the first example in the boost ASIO document. The file name is chan

I have studied ASIO for a long time. It's good! I don't want to talk much about the good words, but I think the author has made the Code a lot easier for cross-platform purposes, but this is also a last resort. This analysis only takes into account the implementation on the Windows platform. I will parse the entire design idea and key code for implementation, and then judge its advantages and disadvantages. I will remove what I think can be removed to

the task first If there is a task in the queue and a Epoll_wait listener event is required, the non-blocking call epoll_wait (the timeout field is set to 0) will be blocked on the epoll_wait until the task is executed. The use of the thread almost reached the extreme. From this function can be known, when using ASIO, Io_servie should be as many as possible, so that it can epoll_wait occupy the most time slices, so as to maximize the response to IO ev
