boost asio

Recently, the code of the new face detection algorithm always prompts WinSock. h has already been included. Someone has provided a solution and reprinted it to remember it. When you start to use the boost: asio library, the following error occurs during compilation: Fatal error C1189: # error: WinSock. h has already been pinned DED Check the boost code that th

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

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 t

Since ASIO uses epoll as the network core, to understand epoll, let's take a look at how libev works. Compared with the huge boost dependency of ASIO, libev is compact, lightweight, and efficient.

This is a created article in which the information may have evolved or changed. Today, on the subway, it occurred to me that it was possible to use the channel in go to easily implement the asynchronous function in ASIO. In fact, ASIO mainly with the use of function variables to hold the code, and it is because C and C + + do not support the reflection, there is no problem in go, the direct use of reflect

If Io_service is the brain of the ASIO library, Post and dispatch are the hands and feet of the ASIO library.Let's take a look at example 1#include The code uses a smart pointer to control the Io_service, using a mutex to control the

The value range of I is [0, 2000) (Left closed and right open). A process is continuously created and each process runs the send-test function. Now let's take

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 first parameter indicates whether it is blocked, in the do_one code: BOOL ok = ::GetQueuedCompletionStatus(iocp_.handle, bytes_transferred, completion_key, overlapped, block ? timeout : 0); If it is false,

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

Before getting familiar with ASIO, familiarize yourself with the BSD socket C/S model.

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

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
