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

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 interface

Recently, I have been studying network-related things and found that my previous understanding of UDP is weak. I am too dependent on TCP and even forget the existence of another UDP. As a result, I randomly searched the UDP socket programming code and materials on the Internet, and found that there was still a connect in the programming example written by someone. I was speechless. Compared with TCP, UDP is an unreliable transmission protocol. When the network environment is poor, using TCP is u

Now we use newlisp to write a tcp client for testing.Program: Chenshu @ chenshu-Beijing :~ $ Newlispnewlisp v.10.4.5 64-bit on Linux IPv4/6 UTF-8 libffi, execute 'newlisp-H' for more info.> (set 'socket (net-Connect "localhost" 8888) 3> (net-send socket "") The aboveCodeExplanation: 1. (net-connect...) is used to connect to the local port 8888. The returned socket file is assigned to the socket variable. 2. (net-send can send a string "a" to the connection represented by socket"

Today I would like to talk about how the network communication library in boost is designed and used, as it has been working with the network recently, and big data processing and machine learning are all inseparable from the final use of the network for on-line deployment. Let's look at all the source code first.#include This is the full source code for the service area.Data is the format of the message, translate_data the definition of the class, wh

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(

Only by looking at the boost source code can we figure out what happened. First, I write data into the vector, and then use boost: ASIO: buffer to construct the vector into a mutable_buffer_1 object. Refer to the document's heavy duty form: http://www.boost.org/doc/libs/1_53_0/doc/html/boost_asio/reference/buffer/overload24.html buffer (24 of 28 overloads)Create

I didn't know what was going on at first, but luckily I had a message printed at each class's destructor.This time I found a tcp_connection (that is, a custom connection Class) to be refactored at the end.So there may be a problem here.Since tcp_connection is derived from the boost::enable_shared_from_thisSpeculation may be that some resources need to be released in advance, without causing some data to be io_service when the resource is released.So I

This should start with a smart pointer. A smart pointer is to dynamically manage a pointer using the construction and destructor of a variable. To put it bluntly, construct -- new; destructor -- delete. We can easily write a smart pointer: templateclassTclassTAutoPtr {public: TAutoPtr () {m_tnewT (); coutTAutoPtr: TAutoPt This should start with a smart pointer. A smart pointer is to dynamically manage a pointer using the construction and destructor of a variable. To put it bluntly, construct --

From the example in the previous section, we can get an inference. If no asynchronous I/O operations are initiated in the connection object, the connection object will be destroyed after the last callback function is executed. I need to prove this inference. If startwork initiates an asynchronous call to wait for data after the connection is established, the connection object will not be destroyed during the waiting period. Once the waiting data arrives, the connection object will be destroy
