1 Introduction Asio is a cross-platform C + + library that is commonly used for network programming, low-level I/O programming, and so on (low-level I/O), with the following structural framework: 2 Using Asio 2.1 Downloads Asio Library is divided into Boost version and non-boost version, please download it on the website. 2.2 Configuration 1) using Qt 5.9.1, i

To understand the basic concept of boost ASIO, here is the synchronous TCP/IP communication implemented by boost ASIO:Server Program section, if you want to keep the socket after the communication, you can dynamically request Socket_type, save the pointer, because Socket_type seemingly can not copy:#include"stdafx.h"#include#includeusing namespaceBoost::asio;using namespacestd;intMain () {Try{typedef ip::tc

Boost::asio Programming-Synchronous TCP The Boost.asio Library is a cross-platform network and a C + + programming library of the underlying IO, which implements a unified asynchronous invocation model using modern C + + techniques. The Boost.asio library supports TCP, UDP, and ICMP communication protocols. The following describes the synchronous TCP mode: Hello everyone! I am the sync way! My main characteristic is the persistence! All operation

most of the reactor patterns used in high-performance network libraries under Linux are implemented, and the Boost ASIO uses Epoll and select to simulate Proactor mode under Linux, which affects its efficiency and complexity .look at the performance of Aboutspeaker's own Linux Reactor network library and ASIO, which is about 1/5 higher than ASIO performance (thro

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

Environment: vs2010, Boost_000046_1, decompress it, and put it in, D: \ boost_000046_1. 1. compile. Most of the boost library's source files are only cast files, so many libraries can be used without compilation. However, some libraries need to compile the source code. ASIO requires compilation. How to compile it? Download bjam.exe from the official boostofficial website and put it under the root directory of the boost source file.

Io_service: The run function will be automatically returned when there are no tasks. This is not convenient for wtl projects. I have mentioned using a loop to run the run function in my previous article, that is not elegant. Today, I found a new method on the Internet and finally found that the io_service: Work class can enable the io_service: Run function to still not return when there is no task until the work object is destroyed. Boost: ASIO: io_s

Http://www.gamedev.net/blog/950/entry-2249317-a-guide-to-getting-started-with-boostasio?pg=4This section adds tasks for Io_service and distinguishes between dispatch and post. 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

implementation Analysis of Boost::asio Io_service the role of Io_service Io_servie implements a task queue, where the task is a function of void (void). Io_servie the two most commonly used interfaces are post and run,post to the task queue, run is the task in the queue until all is finished, and run can be called by n threads. Io_service is a fully thread-safe queue. Interface for Io_servie The interfaces provided are run, Run_one, poll, Poll_one,

Boost::asio Programming-Synchronizing TCP Boost.asio Library is a cross-platform network and the underlying IO C + + programming library, which uses modern C + + techniques to implement a unified asynchronous call model. The Boost.asio library supports TCP, UDP, and ICMP communication protocols. The following describes the synchronous TCP mode: Hello everyone! I am the sync mode! My main feature is perseverance! All the operation to complete or error

After completing the first boost: ASIO-based communication service program, review the concepts used and refer to some materials. We will use a series to summarize how to write high-performance TCP service programs through boost: ASIO. This article describes how to listen to a port and receive connection requests from a single thread. At the same time, the previous "elegant exit" code is also reused. First,

Recently, XMLSocket was added to the server to communicate with Flash. This protocol is actually a string protocol ending with \ 0. To make asio compatible with this Protocol, I have found async_read_until asynchronous reading series from the document. When this function is used in principle, a streambuf and a separator are given. When asio encounters a separator, it returns. You can read the required data

to a remote host asynchronously. For example, the GUI program opens the connection via a button, but we do not want the GUI interface to freeze until the connection is complete. The Boost::asio provides an asynchronous way to connect.Use Bind shared_ptr.#include 　　If you want to pass a Boost::asio object, we generally use the SHARED_PTR smart pointer. Because most objects are non-copyable that cannot be co
