About the author

As an authoritative C ++ expert, besides occasionally using C # and Java to write programs,John TorjoHe contributed most of his programming career over 15 years to C ++.

He also enjoys writing programming-related articles in C ++ Users Journal and other magazines.

In his spare time, he enjoys playing poker and driving fast trains. He has many freelancers, one of which combines his two hobbies, one playing poker and the other programming. If you want to contact him, you can send an email to the john.code@torjo.com.

I would like to thank my friend Alexander Ru Chis, Aurelian Hale, Bela Tibor Bartha, Cristian Fatu, Horia Uifaleanu, niclae Ghimbovschi and Ovidiu Deac. I would like to thank them for their feedback and comments on this book. At the same time, I would like to thank all of you at Packt for your inclusiveness in my frequent missed deadline. Then, I would like to thank Chris Kohlhoff, the author of Boost. Asio, who wrote such a great library.

I will dedicate this book to my best friend Darius.

About reviewers

Béla Tibor Bartha

A professional software engineer who has used multiple technologies and languages for development. Even though he has been developing iOS and OSX applications for the past four years, C ++ has spent some time with him in the development of personal game projects.

I want to thank John because he can review this book.

Niclae Ghimbovschi

An individual developer who has participated in various C ++ projects for more than five years. He is mainly involved in enterprise communication projects. As an avid Linux enthusiast, he prefers to use different operating systems, script tools, and programming languages for testing and experimentation. In addition to programming, he also enjoys cycling, yoga, and meditation.

I want to thank John for letting me review this book.

Preface

Network programming has been around for a long time and is a very challenging task. Boost. Asio provides an excellent abstraction for network programming to ensure that you can use a small amount of programming to create an elegant client/server software. In the process of creation, it can make you experience great fun. But more beneficial: Boost. asio includes some non-network features, using Boost. the code written by Asio is compact and easy to read. If you follow what I have mentioned in the book, your code will be impeccable.

What does this book cover?

Chapter 1: Boost. AsioWhat is Boost. Asio? How to compile it? Some examples are provided. You will find that Boost. Asio is not just a network library. At the same time, you will also be exposed to io_service, the core class in Boost. Asio.

Chapter 2: Basic Principles of Boost. AsioIncluding what you must know: when to use Boost. Asio? We will gain an in-depth understanding of asynchronous programming-a more skillful and fun programming method than synchronization. This chapter also serves as a reference for the development of your own network applications.

Chapter 3: echo server/clientIt will show you how to implement a small client/server application. Maybe this will be the simplest Client/Server application you have ever written. The echo application is a service that sends any message sent from the client back and closes the client connection. We will first implement a synchronous application and then implement an asynchronous application, so that you can easily see the differences between them.

Chapter 4: client and serverWe will discuss in depth how to use Boost. Asio to create a simple client/server application. We will discuss how to avoid defects such as memory leaks and deadlocks. All programs are simple frameworks that allow you to expand and meet your needs more conveniently.

Chapter 5: Synchronous VS asynchronousIt will show you the things you need to consider when you choose synchronous or asynchronous mode. First, avoid obfuscation. In this chapter, we will find how easy it is to implement, test, and debug each type of application.

Chapter 6: Other features of Boost. AsioIt will show you some unknown features of Boost. Asio. Although std streams and streambufs are a little difficult to use, they show their unique advantages. Finally, you will see the late Boost. Asio coroutine, which allows you to write asynchronous code in a more readable way. (Just as it is synchronized)

Chapter 7: Advanced Boost. AsioIt will handle some advanced problems of Boost. Asio. Although you do not need to study them in daily programming, it is helpful to know about them (Boost. Asio advanced debugging, SSL, Windows features, POSIX features, etc ).

What do you need to prepare for reading this book?

To compile Boost. Asio and run examples in this book, you need a modern compiler. For example, Visual Studio 2008 and later versions, or g ++ 4.4 and later versions

Who prepared this book?

This book is a good news for developers who require network programming but do not want to study complex original network APIs in depth. All you need is a simple abstraction provided by Boost. Asio. As part of the famous Boost C ++ library, you only need to add a few extra # include files to convert to Boost. Asio.

Before reading this book, you need to be familiar with the knowledge of Boost core libraries, such as Boost smart pointers and boost :: noncopyable, Boost Functors, Boost Bind, shared _ from_this/enabled_shared_from_this and Boost threads (threads and mutex ). You also need to know the Boost Date/Time. Readers also need to know the concept of blocking and the "non-blocking" operation.

Conventions

You will find that different types of information are distinguished using different styles of text in this book. Examples of these styles and their explanations are given here.

The code in the text is displayed as follows:Io_serviceThe example is enough ".

A piece of code looks like this:

read(stream, buffer [, extra options])async_read(stream, buffer [, extra options], handler)write(stream, buffer [, extra options])async_write(stream, buffer [, extra options], handler)
