Looking at the information of the Boost.asio Library of the day, it is still a little confused. For ASIO's study to continue, at the same time here also recorded the first small example of their own start. It feels better to start with a small example and then to understand what those principles are. Because the conceptual principle is too abstract, with a small example to know how to be a routine. For the ASIO library in the later study will continue
There is a co-libraries in the GitHub organization of the Purecpp community: https://github.com/topcpporg/cpp_featuresRecently there are users to find me, want to know about the Coroutine library in the network performance, so select the standard library has been selected Boost.asio network library asynchronous model to do a horizontal comparison.In the case of small packets and the use of multicore, the network performance of the Coroutine library ASIO
Synchronize Timer
The timer name provided in asio is deadline_timer, which provides the time-out function. First, we will use the simplest Timer synchronization method as an example to demonstrate how to use it.
# Include# IncludeInt main (){Boost: asio: io_serviceIo;Boost: asio: deadline_timerTimer (io, boost: posix_time: seconds (3 ));Timer. wait ();Std: cout
Boost ASIO is a library for Asynchronous Network Communication. Among them, async_write is a common function. However, if it is not used correctly, unexpected potential bugs may occur. For example, the following code:
for (int i=0; i
The code is simple, that is, loop N times and send n buffer blocks. Our goal is to receive buffer1, buffer2 ,......, Buffer n. However, in fact, the above Code is faulty, and the server may receive completely disordered
IO Model
The io_service object is the scheduler in the asio framework, and all asynchronous io events are distributed and processed through it (an io_service object must be input in the constructor of the io object ).
Asio: io_service;Asio: ip: tcp: socket (io_service );
In the asio framework, the main io synchronizati
Boost::asio can perform synchronous or asynchronous operations on I/O objects such as sockets, it is necessary to understand Boost::asio, your programs, and the process of their interaction before using Boost::asio. As an example of a bootstrap, we think about what happens when a socket performs a connection operation, and we start with a synchronous example wher

C + + Boost::asio programming-Asynchronous TCP
Hello, everyone, I'm an asynchronous way.
Unlike sync, I never take the time to wait for those turtle-speed IO operations, I just tell the system what to do, and then I can do something else. If the system completes the operation, the system will notify me by the callback object I gave it before.In the ASIO library, a function or method name in the asynchrono

As I mentioned, to address the problems encountered in boost ASIO, encapsulate ASIO with the following goals:
1. Create a socket and acceptor and no longer construct io_service by yourself. Because the objects in ASIO need to save the reference of io_service,

Ace is a very mature middleware product. It is an adaptive communication environment, but it is too ambitious. There are a bunch of design patterns, and the architecture is layer after layer. It is a little difficult for beginners.ASIO is a basic asynchronous Io library developed by boost. It encapsulates socket and simplifies development based on socket programs.

Over the past few days, I have been working on a large volume of data solutions for linux. I have continuously learned about aio, epoll, libevent, boost: asio. In the past, I only knew that they are both asynchronous and non-blocking, but what are the key points to solve the problem? Through these several days of in-depth understanding, I will summarize them:
Aio is the asynchronous IO implemented by the kernel after linux2.6, or it is the true asynch
